| 20110069914 | DRAWER SLIDE AND LOCKING MECHANISM - A drawer slide with lock mechanism has an elongated outer slide member extendably coupled to an inner slide member. A latch arm or pin is fixed to the inner slide member for latching by a lock mechanism fixed to the outer slide member. The lock mechanism uses a latch receiver that rotates with respect to the lock mechanism and is in a travel path of the latch arm. A lever arm rotates with respect to the lock mechanism and is positionable to block rotation of the latch receiver in a locked position to retain the latch arm. A motor drives a cam to position the lever arm to free the latch receiver from the locked position. | 03-24-2011 |

| 20110181942 | NONLINEAR HARMONIC GENERATION AND DEVICES IN DOUBLY-RESONANT KERR CAVITIES - A nonlinear harmonic generation system is provided. The nonlinear harmonic generation system includes a waveguide channel receives and propagates electromagnetic signals. A resonant cavity is coupled to the waveguide channel. The resonant cavity structure includes a plurality of resonant modes into which electromagnetic energy is coupled during the operation of the system. One of the resonant modes includes a resonant frequency that changes during operation of the system to reach either an input-signal frequency or a harmonic frequency for a majority of the time in which harmonic generation is occurring. Both reflected and harmonic fields are emitted back into the waveguide channel so as to allow efficient harmonic generation at a specified critical input power. | 07-28-2011 |

| 20080252524 | Path-Sharing Transceiver Architecture for Antenna Arrays - A path sharing transceiver array architecture is disclosed. A plurality of channels are linked to antennas of an array for transmitting and receiving wireless signals that are offset in one of phase or time relative to one another. Each channel is associated with a delay element. In the receiving case, an offset signal is received at a first channel, processed, and shifted by a first delay element. The resulting signal is combined with the processed signal of a second, adjacent channel where a phase or time delayed signal is received. The combined signal is then shifted by a second delay element to produce a net signal. The first delay element is used to generate a shifted signal for both the first and second channel. The architecture can be extended to another number of channels. | 10-16-2008 |
| 20080297414 | ULTRA-WIDEBAND VARIABLE-PHASE RING-OSCILLATOR ARRAYS, ARCHITECTURES, AND RELATED METHODS - Variable phase ring oscillators are described that provide a linear phase progression between adjacent elements in an antenna array by providing a symmetric ring configuration of tuned amplifiers and a single phase shifter. The ring topology is coupled to a single PLL that allows for direct modulation and demodulation of arbitrary waveforms without using RF up/down converting mixers. The PLL distributes the transmit waveforms to all antenna elements in the transmit mode and combines the received waveforms in the receive mode without any complicated power distribution network. Ultra-wideband architectures and methods are described that utilize a first reference signal source, a VPRO, and a second reference signal source. Related methods are controlling an array and beam steering are also described. | 12-04-2008 |
| 20100237958 | FEED-BACK AND FEED-FORWARD SYSTEMS AND METHODS TO REDUCE OSCILLATOR PHASE-NOISE - Systems, methods, and apparatus are described that provide for low phase-noise, spectrally-pure, and low-jitter signals from electrical oscillators. An aspect of the present disclosure includes utilization of an open-loop feed-forward phase-noise cancellation scheme to cancel phase noise, or jitter, of an electrical oscillator. Phase noise can be measured and then subtracted, with the phase noise measurement and subtraction being performed at a speed faster than phase noise variations of the oscillator. Another aspect of the present disclosure includes use of a feedback scheme for phase noise reduction. A feedback scheme can be used alone or in conjunction with a feed-forward scheme. Related phase-noise cancellation and/or reduction methods are described. Notch filter and RF amplifier circuits are also described. | 09-23-2010 |

| 20120071307 | APPARATUS FOR AN ABDOMINAL EXERCISER DEVICE - An apparatus for an abdominal exerciser device in the general shape of an adult human cervical spine which acts to fix the position of the neck and cervical spine during a stomach crunch exercise movement is presented. The abdominal exerciser device comprises three major components: the device spine, the cushion assemblies, and the hand straps. The device spine is a bar or tube curved to follow the adult human cervical and upper thoracic spine and provides attachment points for the cushion assemblies and straps. The cushion assemblies are contact points for the exerciser's head and upper back, while the straps allow the exerciser to keep contact with the exerciser device during the exercise movement with minimal force. | 03-22-2012 |
