Abstract: A frequency translator uses a CORDIC phase rotator coupled to a phase accumulator to translate an input signal in frequency. The CORDIC phase rotator performs required phase angle rotations of input vectors using only shift and add operations. Thus, the frequency translator can be readily implemented in hardware. Higher precision arithmetic is used in the CORDIC phase rotator operations than the input vectors contain. To avoid truncation error at the output of the CORDIC phase rotator, stochastic rounding is employed. A dither signal is added to avoid errors due to nonlinear operation of D/A converters, where D/A conversion of the frequency translated signal is required.

Abstract: An apparatus and method are disclosed for processing phone-in prescription requests. The apparatus is in the form of a prescription processing network that includes a prescription processing system and a communication device remotely located from the prescription processing system. The communication device is used to establish a communication channel with the prescription processing system and submit a prescription request over the communication channel. A pharmacist, associated with the prescription processing system, prepares a completed prescription form based, at least in part, on the submitted prescription request. The prescription processing network also includes a pharmacy for receiving the completed prescription form, and filling the prescription request based on the completed prescription form.

Abstract: A GPS receiver acquires carrier frequency and Gold code phase using short segments of a received GPS signal. In one embodiment, a 1-ms segment of the GPS signal is transformed to the frequency domain. This is multiplied by a frequency representation of the Gold code. The resulting product is converted to the time domain, and a peak is detected. The location of the peak corresponds to the code phase. If no peak is located, the carrier frequency is changed. Full- and half-bin steps in carrier frequency are considered. Processing gain is achieved by using longer segments of the input signal, for example 4 or 16 ms and integrating 1-ms segments. Considerations are provided for compensating for the effects of a transition, should it occur in the short segment of the GPS signal being processed. Integrations can be performed using non-coherent and coherent techniques. Adjustments are made for non-integral millisecond segment lengths.

Abstract: Circuitry is used for generating one or more commands to access a ring buffer on an end node device of an advanced switching (AS) fabric. The circuitry includes circuits to receive information for accessing the ring buffer and to generate a current command based on the information. The information includes an address of the ring buffer and a length of data associated with buffer access. The circuitry also includes a controller to determine whether the information is for one command or for plural commands. If the information is for plural commands, the circuits generate the plural commands by updating the information following generation of the current command and by generating a subsequent command using updated information.

Abstract: An apparatus communicates with an advanced switching (AS) fabric. The apparatus includes a transmit engine that generates a request packet for transmission to the AS fabric. The transmit engine associates a first transaction identifier with the request packet. A receive engine receives a reply packet in response to the request packet. The reply packet contains a second transaction identifier. The receive engine compares the first transaction identifier to the second transaction identifier. If the first transaction identifier matches the second transaction identifier, the receive engine decides to store data from the reply packet at an address associated with the first transaction identifier.

Abstract: A manipulator for a fiber optic cable assembly (FOCA) provides microradian accuracy in control of the direction of a beam emanating from the FOCA. Such manipulators can control FOCAs to control the incidence angles of beams at a beam combiner in a beam-combining unit. Accordingly, fewer additional optical elements are required for control of input paths in the beam-combining unit. The manipulator and the beam-combining unit are accurate enough for use in an interferometer that combines beams with different frequencies and polarizations. One such interferometer includes a Zeeman split laser providing a heterodyne beam. A beam splitter separates frequency components of the beams, and AOMs increase the frequency separation between the separated beams. The separated beams can be sent via optical fibers to the beam-combining unit, which combines the beams for use in interferometer optics.

Abstract: A geographic tracking system with minimal power and size required at the mobile terminal collects observation data at the mobile terminal, forwards the data to a processor, which calculates the position. The mobile terminal needs only to gather a few milliseconds of observation data, and to relay this observation data to the processor. The range from the satellite (or other airborne transponder) to the terminal is determined using the known positions of an interrogating transmitter and a satellite, and a known terminal delay between the received signal and the transmission of the return signal, and the round trip time. An arc of locations is determined by computing an intersection of a sphere centered at the satellite having a radius given by the calculated range with a model of the Earth's surface. The candidate points are considered and refined using code phase measurements from a set of GPS satellites.

Abstract: A radio-controlled toy vehicle is provided with four non-steerable wheels, two on each lateral side of the vehicle. In one embodiment, the wheels on each lateral side are drivingly coupled with a separate, reversible motor. The vehicle is steered by controlling the operation and direction of each motor. In another embodiment, the wheels on each lateral side are drivingly coupled with a single reversible motor. The vehicle is steered through one-way clutches which allow the wheels on one lateral side to operate in either a forward or a reverse direction while the wheels on an opposite lateral side always rotate in the same direction. In both embodiments, a pivoting beam is centrally located on one lateral side, with the wheels on that side being rotatably attached to the beam. The pivoting beam provides for infinite ranges of suspension positions. In operation, the vehicle proceeds until it encounters an obstacle.
