Title: Method and apparatus for establishing a link in a wireless communication system
Inventor: BRUCKERT EUGENE J
IPC: G10L15/00
Filed: 1997-08-13
Granted: 2002-05-07
Abstract: A base station system (203, 303) in a wireless communication system (208, 308) establishes a link between a mobile station (200, 300) and a speech recognition system (209, 312). When the base station system (203, 303) determines that such a connection is required, the base station system (203, 303) instructs the mobile station (200, 300) to switch from a first codec (201) specific to human speech to a second codec (202) specific to speech recognition. Only after the switch between codecs in the mobile station (200, 300) does the base station system (203, 303) establish the link between the mobile station (200, 300) and the speech recognition system (209, 312).

Title: Hybrid analog/digital method and apparatus for controlling the transmission power level of a radio transceiver
Inventor: ZIEGLER ROBERT ANTHONY
IPC: H03G3/00
Filed: 1996-05-01
Granted: 2002-03-05
Abstract: A technique for controlling the transmission power level of a transmitter, particularly in a wireless personal communication system, is disclosed. This technique assists in the prevention of interference between transceivers from degrading the quality of transmissions. Transmission power level is controlled through a hybrid circuit containing both digital and analog electronics. The transmission power level is set by controlling both the amount by which a data stream is compressed and the gain of an analog transmit power amplifier. This approach allows adequate control over the transmission power level; it avoids the need for utilizing excessively wide data paths for the digital transmit signals (which may compromise portable terminal battery consumption), or utilizing expensive, hard-to-calibrate analog electronics.

Title: Distillation process to separate mixtures containing three or more components
Inventor: AGRAWAL RAKESH
IPC: B01D3/14
Filed: 1998-10-21
Granted: 2001-07-31
Abstract: A technique is set forth to reduce the heat requirement of conventional distillation processes which separate feed mixtures containing three or more components. The technique provides a great deal of flexibility in adjusting the temperatures of the required utilities including a scenario where the heat requirement is reduced without a need for additional higher temperature (and more costly) heat utility. In this technique, when a liquid bottoms stream (or gaseous overhead stream) containing two or more components is sent from an earlier column to a subsequent column, then a return vapor (or liquid) stream is implemented between the same locations in the two columns.

Abstract: In an appliance such as an oven for cooking food, the invention contemplates a user rotatable, single knob oven control device which provides both discrete and continuous control signals to the appliance controller. The discrete outputs indicate selection of oven features, and the continuous output the desired baking temperature. These inputs are selected by a user in response to rotation of a user interface knob mounted on a control panel. The control panel provides visual indication of oven cooking temperature selections through a first arc around the knob, and user selectable oven features (such as, e.g., OFF/CANCEL, BROIL, and CLEAN) in a second arc around the knob. The control device comprises a hub having a portion adapted to be drivably coupled to the user interface knob. The hub also includes a flange which has at least one cam. The device also includes a variable resistance element having a rotatable shaft in driving engagement with the hub. This element provides a variable resistance output in response to rotation of the shaft through the first arc. Additionally, the device includes a push button switch which is located external to the variable resistance element. The switch is also located in proximity with the flange such that rotation of the hub will bring the cam in contact with the switch to actuate it.  This switch provides a discrete output when actuated by the cam to indicate a selection of one of the oven features.

Abstract: A method for identifying barley with good brewing properties using the thermostability of the barley .beta.-amylase as an indicator. The thermostability of the barley .beta.-amylase significantly affects the degree of the apparent attenuation limit. A method for determining the enzyme activity of an extract solution from one barley seed, an indirect method by an isoelectric point, and an indirect identifying method by DNA polymorphisms of the region containing the .beta.-amylase structural gene have been developed as a method for determining the type of thermostability for a barley .beta.-amylase. The selection method is not affected by environmental or climatic conditions.

Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor receives an airflow signal from a pressure transducer coupled to a port at a mask.    The microprocessor controls a servo that in turn controls the fan motor and thus the pressure of air delivered by the blower. The blower is coupled to a subject's mask by a conduit. The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.
