IPC: H01J7/32
Filed: 1991-03-07
Abstract: BOOSTER BATTERY ASSEMBLY         ABSTRACT OF THE DISCLOSURE:        A booster battery assembly is provided, where the booster battery is intended for use to provide additional energy to vehicle batteries, while connected in parallel with such vehicle batteries, so that a sufficient source of cranking current is available.   Moreover, it is important for the terminal voltage of the vehicle battery as boosted by the booster battery assembly to be above about at least 6.0 to 8.4 volts for an average automobile in order for ignition to be initiated and maintained during cranking.  The booster battery assembly is portable, or it may be permanently installed in the vehicle, but isolated from the vehicle battery.  In any event, the booster battery assembly of this invention comprises a battery of the same terminal voltage as the vehicle battery but of much smaller capacity.  The booster battery may be charged from the vehicle battery during a time when the vehicle alternator is operating, or it may be recharged from an AC source.   It is also contemplated that the booster battery may be a one-shot,  reserve type standby battery.  The booster battery assembly is not intended to replicate an automobile battery, merely to provide some additional starting energy to permit engine cranking and to maintain spark ignition during cranking.

Title: Method and apparatus for dynamic channel bandwidth allocation among multiple parallel video coders
Inventor: HANG HSUEH-MING
IPC: H04N7/26
Filed: 1991-08-26
Abstract: A dynamic channel allocation unit for specifying a bit rate for each video coder in a set of parallel video coders comprising an overall video coder is disclosed.  The dynamic channel allocation unit is supplied from each individualvideo coder with an average frame quantization  step size for the previous frame and the average number of bits produced per pel. For the current image frame the dynamic channel allocation unit computes a set of channel sharing factors, i.e., the percentage of the total channel bandwidth to be allocated to a particular video coder. One channel sharing factor is computed for each individual video coder. Individual members of the set of channel sharing factors may be further refined to reflect the prior history of the channel sharing factor for their corresponding  coder. Additionally, the set of estimates may be normalized to reflect the actual number of bits that can actually be produced by each individual video coder.

Title: Saccharide compositions, methods and apparatus for their synthesis
Inventor: ROTH STEVE
IPC: A61P31/04
Filed: 1991-04-11
Abstract: A method for preparing saccharide compositions is disclosed. The method is reiterative and comprises the following three steps:  (i) a glycosyltransferase capable of transfering a preselected saccharide unit to an acceptor moiety is isolated by contacting the acceptor moiety with a mixture suspected of containing the glycosyltransferase under conditions effective to bind the acceptor moiety and the glycosyltransferase and thereby isolate the glycosyltransferase. The acceptor moiety is a protein, a glycoprotein, a lipid, a glycolipid, or a carbohydrate. (ii) The isolated glycosyltranferase is then used to catalyze the bond between the acceptor moiety and the preselected saccharide unit. (iii) Steps (i) and (ii) are repeated a plurality of times with the intermediate product obtained in the first iteration of the method being used as the acceptor moiety of the second iteration.

Patent CA-2066852-A1 (CA)
Inventor: HUMMEL WILLIAM F JR
IPC: B64G1/28
Filed: 1992-04-22
Abstract: Method and apparatus for controlling the two-axis rate and position as well as the linear elevation of a momentum wheel platform supported by three jackscrews driven by stepper motors. By tilting the momentum wheel, a control torque is produced in the plane orthogonal to the nominal wheel spin axis. When all three actuators are operational, the control transformations are made unique by constraining the sum of the actuator extensions to be zero. When one actuator has failed, the above constraint is eliminated and the failed actuator is constrained to its measured value. Momentum wheel platform rotational rate commands generated by the roll/yaw control system are first integrated to give desired gimbal angles, and then transformed into jackscrew extensions. Jackscrew step commands are computed as the difference between these desired extensions and the current positions of the jackscrews. The position of each jackscrew is maintained by accumulating the step commands. The desired extensions are also back-transformed to compute gimbal angles that are fed back to the roll-yaw state control system. In ground command stepping, the momentum wheel platform steering method operates exactly as described above, except that relative jackscrew step commands from a ground station are utilized instead of the step commands computed in the rate following configuration.
