A one-dimensional electromagnetic band gap (EBG) waveguide phase shifter electronically scanned array (ESA) horn antenna utilizes a linear array of EBG waveguide phase shifters for scanning and radiating a beam. A linear array feed feeds the linear array of EBG waveguide phase shifters. A horn directs radiation from the linear array of EBG waveguide phase shifters. Each of the EBG waveguide phase shifters is a waveguide with vertical and horizontal sidewalls. EBG devices are located on the vertical waveguide walls to shift phase to scan the beam.

An apparatus and method for providing an indication of a type and/or a condition of a note passing through the apparatus includes a note transport (12) which moves the note past transversely spaced spot sensing assemblies (18). Each spot sensing assembly includes four emitters (32). Each of the emitters produces radiation at different wavelengths. The spot sensing assemblies include a reflectance detector (20) and a transmission detector (22) which are disposed on opposed sides of the passing note. The emitters direct radiation onto test spots (34) on the passing note. Radiation reflected from and transmitted through the test spots is detected by the respective reflector and transmission detectors. A control circuit (24) produces sensed values that correspond to the detected radiation. A data store in operative connection with the control circuit comprises memories (138) that include stored data representative of transition and reflectance values for know note types. The control circuit calculates a level of correlation between the stored values and the sensed values. By comparing the correlated values to threshold values, the control circuit is operative to determine the type of note and other conditions such as if a note is worn, soiled, or a doubles note.

A system for supplying power wirelessly to a remote mobile device including (i) a transmitting unit for directing radiation into the region of the mobile device, the transmitting unit having a gain medium with a front surface directed towards the space, and a retroreflector on its back surface, and (ii) a receiver unit connected with or attached to the mobile device for receiving radiation transmitted from the transmitting unit. The receiver unit includes (i) a retroreflector for reflecting part of the radiation received from the transmitting unit back in the direction of the transmitting unit, where it is amplified and retransmitted back in the direction of the receiver unit, and (ii) a power detection element for absorbing that part of the radiation not reflected by the retroreflector, and converting it to electrical power for use by the mobile device. Modulation of the transmitted beam enables it to transmit data also.

A phosphorescent sunroof for transmitting light into a vehicle includes a roof assembly comprising a roof having an opening, and a panel adapted to fit the dimensions of the opening. The panel is made of a light-transparent component that transmits light from an external source into the vehicle. The panel includes a phosphorescent material that is excited or made to glow by the external light source without the use of vehicle power. The panel glows for a period of time following exposure to the external light source to allow visibility inside the vehicle and provide aesthetic qualities. Further, the phosphorescent material scatters or diffuses incident light transmitted through the panel, thereby reducing the direct radiation of light and heat load into the vehicle. Also disclosed is a method for providing light into an interior of a vehicle with the sunroof panel.

This invention is directed to an optically-based method and system for analyte detection using solid phase immobilization, specific analyte labels adapted for signal generation and corresponding processes for the utilization thereof. The enumeration detection method disclosed herein narrows the area for signal observation, thus, improving detectable signal to background ratio. The system is comprised of a platform/support for immobilizing a sample stage having a labeled sample (analyte complex) bound thereto, a radiation source, an optical apparatus for generating and directing radiation at said sample and a control that obtains data and then conducts analyses using digital image data. Upon engagement of the system, the sample generates a signal capable of differentiation from background signal, both of which are collected and imaged with a signal detector that generated a sample image to a data processing apparatus. This apparatus receives signal measurements and, in turn, enumerates individual binding events. Generated signal may be increased via selected mass enhancement. The invention, enumeration assay methodology detecting individual binding events, may be used, for example, in analyses to detect analyte or confirm results in both research, commercial and point of care applications.

Radiosurgical techniques and systems treat behavioral disorders (such as depression, Obsessive-Compulsive Disorder (“OCD”), addiction, hyperphagia, and the like) by directing radiation from outside the patient toward a target tissue within the patient's brain, typically without imposing surgical trauma. The target will often be included in a neural circuit associated with the behavioral disorder. A cellularly sub-lethal dose of the radiation may be applied and the radiation can mitigate the behavioral disorder, obesity, or the like, by modulating the level of neural activity within the target and in associated tissues. Hypersensitive and/or hyperactive neuronal tissue may be targeted, with the radiation downwardly modulating hyperactive neuronal activity. By down-regulating the activity of a target that normally exerts negative feedback or a limiting effect on a relevant neural circuit, the activity of the circuit may be increased.

A method and an apparatus relating to an OFDM data communications system where the sub-carriers are modulated using differential quadrature phase-shift keying (DQPSK). The multi-carrier transmitted signal is directly generated by means of summation of pre-computed sample points. As part of the multi-carrier signal generation, a signal for the guard interval is established. In an acoustic application of this approach, direct radiation of the sub-carrier approach is facilitated. Symbol synchronization in the receiver is based on signal correlation with the missed sub-carrier. Separation of the sub-carriers in the receiver by means of correlation of the received signal and reference signals that are derived from a table of pre-computed values. Optimal non-coherent processing of the sub-carriers without any phase tracking procedures is achieved.

The light source layer is held between the detection layer and the object to be imaged. The light-blocking unit is arranged in such a manner as to block the direct radiation of at least part of the light radiated from the light source units to the detection elements.
