Show moreA robotic cane may include a grip handle, a cane body extending from the grip handle at a first end, a motorized omni-directional wheel coupled to a second end of the cane body, a balance control sensor, and a controller module. The balance control sensor provides a balance signal corresponding to an orientation of the robotic cane. The controller module may receive the balance signal from the balance control sensor and calculate a balancing velocity of the motorized omni-directional wheel based at least in part on the balance signal and an inverted pendulum control algorithm. The controller module may further provide a drive signal to the motorized omni-directional wheel in accordance with the calculated balancing velocity. The calculated balancing velocity is a speed and direction of the motorized omni-directional wheel to retain the robotic cane in an substantially upright position.

Show moreMethods for the crystallization of nano-size crystals of molecular organic compounds while operating at a low supersaturation. The methods are based on controlling the domain size available during the crystallization process. In one exemplary method, microcontacted printed self-assembled monolayers (SAMs) with local domain area sizes ranging up to 2500 .mu.m.sup.2 and fabricated SAMs generated from electron beam lithography, are employed to control the size, orientation, phase, and morphology of the crystal. In another exemplary method, a continuous micro-crystallizer having a vessel diameter of 25 microns or less is used to ensure that that the maximum size of the crystals in at least one dimension, ad preferably two dimensions is constrained by the vessel itself. The methods allow control of supersaturation and growth conditions, as well as manageability over crystallinity and polymorphism, and each method's domain size has the potential for further reduction.

Show moreThis invention relates to a method and device for continuously removing and concentrating specific molecules or substances from a gas stream and depositing such molecules or substances in a liquid film stream in a controlled and quantitative fashion. The device includes a hollow tetrafluoroethylene tube or a hollow tube having an inner surface coating of tetrafluoroethylene. The inner surface of the tube is etched by means of a chemical etching agent. An inlet/injector is attached to the outer circumference or inlet, circumferential face of the tube. The inlet/injector has liquid dispersion ports uniformly distributed around the circumference of the processor tube whereby a surfactant containing liquid may be uniformly dispersed from the inlet/injector onto the inner wall of the processor tube where it may flow, in a thin film manner, from the inlet of the tube to the outlet of the tube. The inlet/injector also has a gas injection port whereby a gas containing the molecules or substances sought to be removed and concentrated can simultaneously be injected into the top hollow portion of the tube. An outlet cap is attached to the outer circumference or outlet circumferential face of the tube. The outlet cap has a liquid collection well with a port or other means whereby the liquid flowing down the inner wall of the tube can be collected and transported to an analyzer. The outlet cap also has a gas port whereby the sample gas undergoing analysis can be removed from the tube and vented, treated or otherwise disposed of.

Title: Technique for Establishing a Virtual Backbone in an Ad Hoc Wireless Network

Show moreAn algorithm on a computer readable medium for efficiently creating a message efficient virtual backbone in a wireless ad hoc network utilizes three phases to establish an efficient network among the independent transceivers of a wireless ad hoc network. Independent transceivers within the transmission range of each other are neighbors. A leader election and tree construction phase constructs a tree of neighboring transceivers with one transceiver being designated the root and with each transceiver establishing and recording its location in the tree structure and the identifiers of its neighbors; and reporting when the tree is established. A level calculation phase determines the level of each transceiver away from the root transceiver, with each transceiver recording the level of its neighbors. Precedence for each transceiver is established with consideration of each transceiver's tree level and identifier, with tree level being paramount in deciding precedence; and reporting when the levels of the tree are established. A backbone construction phase establishes all transceivers as a dominator or a dominatee, with the dominators forming the network backbone and the dominatees all being neighbors to a dominator. Within the network each transceiver only needs to know the information of its neighboring transceivers.

Show moreA waveguide structure is emplanted in the earth to bound a particular volume of an earth formation with a waveguide structure formed of respective rows of discrete elongated electrodes wherein the spacing between rows is greater than the distance between electrodes in a respective row and in the case of vertical electrodes substantially less than the thickness of the hydrocarbonaceous earth formation. Electrical power at no more than a relatively low frequency is applied between respective rows of the electrodes to deliver power to the formation while producing relatively uniform heating thereof and limiting the relative loss of heat to adjacent barren regions to less than a tolerable amount. At the same time the temperature of the electrodes is controlled near the vaporization point of water thereat to maintain an electrically conductive path between the electrodes and the formation.

Show moreRe-entry residential communities are an integral part of the criminal justice system. They focus on re-entry prepartion, including job training and drug treatment. These group homes are located in the community where inmates serve a period of time after being released from federal prison, in order to prepare for reentering the community. The inmates are required to go outside during the day to work or participate in community services. Law offenders are housed in penal establishments as a punishment not for punishment. Preservation of personality & prevention of deterioration call for as high a priority as efforts to bring about the inmates’ re-entry into the society. Hence the concept of correction, reformation & rehabilitation of prison inmates should come to the forefront of any community correction center’s adminstration.

Show moreA peer-to-peer (P2P) file sharing system is provided with an enhanced search method for a client node therein. A search from the client contains a primary search of metadata words and a secondary search of content file keys taken from the primary search results. The results of the secondary search are then used to rerank the results of the primary search before the client displays the results of the search to the user. Metadata distribution schemes can also be used to further enhance the utility of the system. Enhanced P2P file searching accuracy is thus provided. Applications for selective peer-to-peer communication may further be employed.

Show moreA blank for forming a stencil screen for silk screen or electrostatic stencil printing is disclosed. The screen includes a resilient, high tensile strength, porous substrate such as a monofilamentary nylon or stainless steel 200-mesh screen. A light radiation absorbent, self-combustible, ink-resistant, ink-impervious and tough film is applied to the screen, suitably a combustible black nitrocellulose film or a black cellulose ether film containing finely dispersed nitrate or perchlorate. The film is selectively removed by directly pulsing high-intensity light of over 10 joules per square inch for a short duration of 1 to 50 milliseconds in the form of an image pattern to ignite and completely combust the film only in said areas during the duration of the pulse.

Show moreA magnetic transducer head having a coupling gap of controllable effective longitudinal dimension. In one embodiment a gap spacer of magnetic material is energized by bias current and/or signal current during recording while being deenergized during playback to provide a larger coupling gap for recording than for playback. Recording gap size may be controlled dynamically, or a very high frequency bias current such as 100 mhz may be supplied to the magnetic gap spacer. A magnetic head may have a zero gap dimension when the magnetic gap spacer is deenergized to prevent any substantial residual external field. An electro-magnetic transducer head with the electric circuit portion including a path through the electrically conductive magnetic corepiece at the transducer gap, thus concentrating the gap field and mininizing core losses at very high bias or signal frequencies.
