Abstract: Adenosine deaminase gene (ADA gene) is used as a selectable/reporter gene for plant cells and plants.  When introduced into plant cells, the ADA gene makes the cells resistant to inhibition by 2-deoxyadenosine or an analog, so transformed cells can be separated from non-transformed cells by culturing a cell mixture in a medium containing 2-deoxyadenosine or an analog in amounts that inhibit normal plant cells.  A single vector may be constructed containing an ADA gene from any source (e.g. a mouse ADA gene) and an additional gene-of-interest to be introduced into plant cells. The vector may then be introduced into the cells by such a route as Agrobacterium infection or micro projectile bombardment.  The presence of the ADA gene in successfully transformed plant cells may be confirmed by cultivating the cells in a medium containing 2-deoxyadenosine or an analog in the presence of a material that changes color in the presence of ammonia. Observation of a color change confirms the presence of the gene.  DNA constructs containing both ADA genes and foreign genes-of-interest may be constructed, e.g. plasmid pRD360-ADA (ATCC 69459).

Granted: 2001-11-27
Abstract: The construction of display devices often involves the replication of a single pixel design a large number of times. Full colour display devices are often constructed on the principle of utilising multiple primary colours in order to form a final destination colour. Previously, the degree of complexity of the pixel arrangement devoted to each primary colour was substantially the same. The present invention discloses devoting a variable degree of complexity to each primary colour in a pixel layout depending on the perceptual response of the human eye to the particular primary colour. For example, there is disclosed a pixel arrangement having red, green and blue primary colours wherein substantial complexity is devoted to the green primary colour with a lesser complexity devoted to the blue primary colour.

Granted: 2000-02-01
Abstract: A lighter weight helmet mountable display (HMD) that is easily adjustable to accommodate variable inter-pupil-lary distances includes substantially parallel left and right optical channels, and projects left and right images onto the helmet's visor.  Each channel includes light sour-ces that form a complete scan line of the image, and pro-ject luminance patterns for successive scan lines through a lens which reduces the light's divergence.  A deflector is moved to deflect successive luminance patterns back through the lens so that the lens focuses the patterns onto successive scan lines on a back projection screen.   The screen emits luminance patterns in response to the incident luminance patterns for each successive scan line to project the image onto the visor.

Abstract: An improved PSA process for separating at least one non-preferentially-adsorbable first gas, such as oxygen and argon, from a gas mixture, such as air, containing said first gas and one or more selectively-absorbable second gases.  It involves novel steps of simultaneous equalization and evacuation followed by simultaneous feed and product gas repressurization of PSA beds.  This results in an overall faster and more efficient cycle with 100% utilization of a pressure-reducing means, such as a vacuum blower, and a reduction in power use of about 15%.  The invention involves overlapping of various steps of the PSA cycle to reduce total cycle time and thus improve productivity.

Abstract: A method for reducing power consumption in a cellular telephone by placing the receiver in a sleep mode when it is determined that the received signal has a sufficiently high quality. The duration of the sleep mode is extended by eliminating the need to resynchronize the receiver clock to the transmitter clock using dotting sequence and synchronizing data in the transmitted control data received after a sleep cycle. This is accomplished by resynchronizing the phase of the symbol clock to the phase of the transmitter clock after a sleep cycle utilizing the respective phase relationships to a low frequency, low power maintenance clock in the receiver which maintains time (and hence edge information) during the sleep mode until reception of the next data frame must begin. The maintenance clock is preferably an off-the-shelf oscillator of the type used in wrist watches. At a specified tick of this clock, which is known to the receiver before it goes to sleep, the high-speed system clocks are turned on in preparation for reception of the next frame of data. Since the phase relationship of the symbol clock to the maintenance clock prior to the sleep mode was known, the phase of the symbol clock is readily recreated after the sleep cycle from the known phase of the maintenance clock, which is never turned off.

Title: Solid state overload relay mechanism
Inventor: EDWARDS STANLEY H JR
IPC: H01H71/10
Filed: 1995-10-13
Granted: 2005-08-23
Abstract: A solid state overload relay mechanism designed for minimizing the forces required to open an electrical contact associated therewith in the event of a current overload in a protected circuit, and further designed for overcoming residual magnetism in a solenoid initiating the opening of the contact. The contact includes a pair of stationary contacts supported by a base and a pair of movable contact supported by a contact carrier. A latch defines a notch which is normally engaged with a lever. When so engaged, the contact carrier is positioned such that the movable contacts are in contact with the stationary contacts. When the lever becomes disengaged from the latch, the contact carrier is moved and contact between the movable contacts and stationary contacts is broken. The latch is provided with a counterbalance weight to aid in minimizing the force required to return the latch to its original position after the mechanism is tripped. A latch arm extends away from the latch into the path of the lever such that as the lever travels to its extent in an arcuate path, the lever imparts motion on the latch to return it to its initial position, if such has not already occured. An auxiliary stationary contact pair is supported by an auxiliary stationary contact housing and may be selectively installed ineither a normally closed or a normally open position.

Abstract: In a multi-channel acoustic echo cancellation, received signals in a plurality of channels are radiated as acoustic signals by a plurality of loudspeakers, received signal vectors in these channels are combined into a combined vector and a rearranged received signal vector in the case of at least two channels being exchanged is generated. By inputting the combined received signal vector into an echo replica generating part which simulates echo paths from the loudspeakers to at least one microphone, an echo replica is generated. The echo replica is subtracted from an echo output from the microphone to obtain a residual echo. Based on the relationship between the received signal vector and the corresponding residual echo and between the rearranged received signal vector and the corresponding approximated residual echo, an adjustment vector is obtained which is used to adjust the estimated echo path vector representing an impulse response of the echo replica generating part.
