US Classification:

704500, 700 94, 704E19001

Abstract:

Systems and methods are disclosed for the management of memory used in a crossfading operation in an electronic device. In one embodiment, a processor is used to alternately decode two audio streams, one which is being faded out and one which is being faded in to implement a crossfade. The two audio streams may be encoded in the same or different formats and may be alternately decoded such that resource usage is reduced. The amount of decoded data of both audio streams and other parameters may determine which audio stream is to be actively decoded. In certain embodiments, the decoded data may be stored in a circular buffer, and a delta is determined between the decoded data and the empty space of the buffer.

Texas Instruments Incorporated - Dallas TX

International Classification:

H01S 3097

US Classification:

372 85

Abstract:

A laser transmitter is comprised of a power converter connected to a power conditioner for converting the preregulated dc power to high voltage dc required for laser discharge. A pulse forming network is connected to the power converter, for generating short, high voltage high current pulses. A laser cavity is connected to the PFN for generating laser pulse beams in response to the PFN output. The laser cavity includes a housing with two thermal-expansion-matched metal electrodes sandwiched between opposing preionization electrodes mounted in wells formed in the ceramic housing. The ends of the wells are ceramic to form dielectric between the cavity electrodes and the preionization electrodes for capacitively coupling the preionization electrodes for cavity chamber and producing coronas in the laser cavity which produce UV radiation in the cavity without arcing. The laser cavity has glass-frit-sealed metal end-caps, a solder sealed out-coupler assembly, a total reflector mirror and total reflector mirror adjustment mechanism.

International Classification:

US Classification:

356 5

Abstract:

A forward looking infrared (FLIR) energy imaging device has been found to include components which are required by the receiver portion of a long-wavelength rangefinder. For example, the FLIR collecting lens system which focuses energy from a scene onto a sensitive, cooled detector array duplicates the function which must be performed by the laser rangefinder receiver. Thus an integrated laser/FLIR rangefinder comprises a laser transmitter for illuminating a target, and an IR energy optic channel having a FLIR for receiving IR energy and producing a visible image representative thereof, said FLIR including an afocal lens system for collecting and focusing energy from the target and energy from the laser return having a wavelength compatible with the band pass of the IR optics and detector onto a cooled sensitive detector. In one embodiment the cooled detector is one of the center detectors of the FLIR detector array, in another embodiment the laser return energy collected by the FLIR afocal lens is reflected by a reflecting chopper, inserted in the FLIR optical path during the dead time generated for scan interlace, to a detector other than one of the center detectors in the array and unused by the thermal imager, or in still another embodiment the laser return detecting detector is a detector other than the cooled detector's of the FLIR detector array and includes a separate cooler. The laser return detector is connected to a laser preamplifier for producing a laser return signal for the laser rangefinder electronics.

Abstract:

A method of managing payments between a payor and a payee includes receiving by the payee a letter and a negotiable instrument made payable to the payee. The letter contains a uniform resource locator (URL) of a web page configured to create an online account responsive to transaction data from the payee. The transaction data includes verification information verifying and associating the payee to the payor and includes the payee's bank account information. The payee can receive the payment via an electronic fund transfer or by depositing the negotiable instrument at a financial institution. A payment system includes a negotiable instrument made payable to the payee and a letter containing a URL of a web page configured to create an online account responsive to verification information verifying and associating the payee to a payor and responsive to the payee's bank account information.
