Title: Biosensor device and method
Inventor: HODGES ROBERT S
IPC: C12Q1/68
Filed: 1997-04-25
Abstract: A biosensor apparatus for detecting a binding event between a ligand and receptor. The apparatus includes an electrode substrate coated with a high-dielectric hydrocarbon-chain monolayer, and having ligands attached to the exposed monolayer surface. Binding of a receptor to the monolayer-bound ligand, and the resultant perturbation of the monolayer structure, causes ion-mediated electron flow across the monolayer.

Title: Coaxial cable protection device
Inventor: SNIEZKO OLEH J
IPC: H04N7/10
Filed: 1998-11-03
Abstract: A coaxial drop cable safety device is used for cable television, data and telephony applications. The device is used on buried drop cable where 60 Hz powering voltages applied to the drop cable exceed low voltage safety limits and where the drop cable is buried at depths which is less than the minimum required to meet electrical safety codes. Tap end and premise end units are connected to the drop cable. The tap end unit applies a DC voltage to the center conductor of the drop cable. A monitoring circuit in the tap end unit monitors the center conductor DC voltage to a fault from the center conductor to ground along the drop cable.  The tap unit will immediately remove the powering voltage In the event of either an open or faulted condition on the center conductor along the entire length of the drop cable. Additionally, while providing fault protection for the low frequency powering circuit due to tampering or damage to the cable, the fault monitoring circuit allows the high frequency television, data and telephony signals to pass with little or no impediment.

Patent CA-2262824-A1 (CA)
Title: Buffer overflow and underflow control for facsimile transmission
Inventor: RIESER JACK H
IPC: H04N1/00
Filed: 1999-02-24
Abstract: In a facsimile system, buffer underflow is prevented by forcing the transmit pointer to wait at a current end-of-line (EOL) symbol and transmit fill bits until there are at least two EOL symbols stored in the buffer. Buffer overflow is controlled by selectively dropping lines if the write pointer approaches too close to the transmit pointer and the difference between successive lines is sufficiently small (selective line-dropping), dropping lines whenever a permitted maximum buffer size is exceeded, and gradually changing the permitted distance between transmit and write pointers and permitted maximum buffer size as the image is scanned to accomplish a smooth buffer flushing.

Title: Dual control analog delay element
Inventor: LEE KI-JUN
IPC: H03K5/13
Filed: 1999-02-26
Abstract: The invention is a delay element for simultaneous coarse and fine control of delay of an input clock signal.

Title: Method and system for processing measurement signals to obtain a value for a physical parameter
Inventor: WHITE JEFFREY S
IPC: G01N29/34
Filed: 1997-11-21
Abstract: A method and system are disclosed for processing time-varying measurement signals (28) to obtain a value for a physical parameter by extracting frequency information from the signals (28). The frequency information includes at least one desired frequency. The frequency information is converted to a value for the physical parameter. Extraction is performed by transforming discrete time ultrasonic signals to a Z-domain (182) and converting at least one zero or pole in the Z-domain to the desired frequency and its decay rate. The measurement signals may be coherent light signals (24, 26, 28) which are frequency modulated based on the propagation of longitudinal waves in the object. For a static film, the physical parameter may be thickness of a cured layer. When the object is a dynamic curable film, its thickness changes over time from an initial value, to an intermediate value, and to a final value.
