Title: Isolation and characterization of the growth hormone releasing hormone receptor
Inventor: THORNER MICHAEL O
IPC: G01N33/53
Filed: 1993-06-22
Abstract: Growth hormone releasing hormone (GHRH) receptor binding has been characterized using a unique binding assay utilizing iodinated GHRH probes. Photoaffinity GHRH probes have been constructed which allow for photolabeling and characterization of the receptor. In addition, high affinity biotinylated GHRH analogs have been constructed. Solubilization of GHRH-R/GHRH complexes and extraction of specifically bound GHRH using a mild detergent solution, followed by affinity chromotography, leads to a substantially purified GHRH-R isolate.      Electrophoretic treatment of the GHRH-R isolate produces GHRH-R of sufficient purity to conduct sequencing of the receptor.

Title: Active noise reduction
Inventor: NADIM MOHAMMED
IPC: G10K11/178
Filed: 1992-04-09
Abstract: Primary vibrations (N), e.g. acoustic noise or vibration from a source thereof such as a motor, are cancelled by secondary vibrations (C) produced by an actuator (2) driven by a controller (3) that is responsive to an error signal (E) detected by a detector (4) and representative of the residual or difference between the primary and secondary vibrations. The controller samples the er-ror signal (E) during successive sampling periods determined by a synchronising signal (syn) taken from the motor. The secon-dary vibrations C n+1 for a sampling period n + 1 are determined as follows: C  n+1 = C n -µE n SGN(l/~], where C n represents the secondary vibrations produced during a preceding sampling period (n); E n represents the detected error signal for said preceding period n, H represents the transfer coefficient between the actuator (2) and the detector (4) and µ is a scaling fac-tor where 0 < µ < 1. The apparatus is in one embodiment configured as an add-on unit for a personal computer (PC) including circuit board which fits into an expansion slot of the PC.

Abstract: Voice, facsimile, and electronic mail messaging is integrated in a system (FIG. 1) that converts e-mail messages into voice-and-fax messages. An e-mail message (400) is parsed into voiceable, prose, segments (403) and non-voiceable,non-prose, segments (404). Prose segments are converted into voice message segments (503) via text-to-speech facilities. Each non-prose segment is converted into a fax segment (504). Voice pointers (505) to fax segments are inserted into the voice message, in places corresponding to the non-prose segments in the e-mail message. The voice file (500) and fax file (510) are then stored for subsequent delivery of the message as an integrated voice-and-fax message. Conversion of integrated voice-and-fax messages into e-mail messages is likewise envisioned.
