Granted: 1994-01-25
Abstract: ABSTRACT         The invention relates to an apparatus for the absorption cooling of a fluid, in particular air.  Two separate mutually independent but interacting absorption cooling devices are provided, the cooling system of one of the two devices being used for cooling the absorbent liquid of the other device, this liquid, after dilution by the fact of having absorbed steam, being boiled by heat provided by condensing steam resulting from boiling the diluted absorbent liquid of the initially considered absorption device by means of an external burner.  The pressure in each component of the absorption device used for directly cooling the air is less than the pressure in the corresponding component of the other device, the absorbent liquid of which is cooled by external cooling fluid.  The two devices are provided with heat exchangers cooled with air, such two heat exchangers being serially arranged so that the same air flow passes through them.

Abstract: A subband coding device has band-pass filters for band-limiting an input signal into band-limited signals having different frequency bands and downsampling circuits for downsampling the band-limited signals into subband samples.  The input signal represents signal samples variable in one-dimensional or two-dimensional space.  The subband coding device has a coder for coding the subband samples into a subband coded signal by classifying the subband samples into sample groups of classified samples and by scanning the classified samples of each of the sample groups across the frequency bands.  The classified samples of each of the sample groups are selected from the subband samples in accordance with sampling instants of the signal samples and in accordance with combinations of the sampling instants when the signal samples are variable in the one-dimensional and the two-dimensional spaces, respectively.

Title: System and method for controlling drill bit usage and well plan
Inventor: HOLBROOK PHILIP
IPC: E21B12/02
Filed: 1993-03-31
Granted: 2000-07-11
Abstract: Hardware, software and methods for controlling the usage of well drill bits and other aspects of well drilling plans. At least a portion of a given well is drilled with a given drill bit. An abrasive-wear-affecting variable (drilling strength) for the lithology which has been most recently drilled with the bit is continually evaluated. The current abrasive wear of the bit by the total lithology which has been drilled thereby is continually calculated, based on the abrasive-wear-affecting variable. Continued use or retirement of the bit is controlled in accord with the wear calculation. Relative pore pressure at the current site of the drill bit is a useful by product which can be independently used to control other aspects of the well drilling plan, e.g. mud weight and the setting of casing.

Title: Prioritizing a multiple access channel in a wireless telephone system
Inventor: FARWELL CHARLES YEOMANS
IPC: H04B7/26
Filed: 1993-08-31
Granted: 1998-09-15
Abstract: Base stations responding on a shared channel to a registration request message received on another shared channel from a wireless mobile unit with the base station to which the mobile unit is assigned transmitting in a first time slot and the other base stations transmitting in a time slot determined by the strength of the received signal from the mobile unit. If two base stations respond to the registration request message in the same time slot and the assigned base station does not respond, the mobile unit determines whether there is a response in a time slot which is earlier in time to the first time slot than the collided time slot. If the collided time slot is earlier in time than any other time slot in which a response is received, the mobile unit transmits a second registration request message specifying the collided time slot. Each of the base stations that had responded in the collided time slot responds by sending a base reply message in a random time slot, and the other base stations do not respond to this second registration request message. The mobile unit selects one of the base reply messages in a random time slot.

IPC: C12N5/071
Filed: 1994-12-30
Granted: 2000-02-01
Abstract: A multiple-loop temperature controller using RTD sensors is continuously calibrated by performing a zero or full scale calibration during each operating cycle. An arrangement of four multiplexers is used to successively connect each RTD sensor to a pair of current sources and an A/D converter, thereby allowing the current sources and A/D converter to be shared among all of the RTD sensors.      Measurement errors are minimized by using the same multiplexers for temperature measurement and calibration, with calibration being performed by connecting the multiplexers to a ground reference or precision resistor.  Interrupt-driven temperature loop processing is used to reduce A/D conversion delays, thereby allowing high-precision A/D converters with long settling times to be used. The multiple-loop temperature controller is advantageously utilized in an automated blood culturing system requiring precise control of sample temperatures.
