Patent CA-2080067-A1 (CA)
Inventor: INKPEN STUART
IPC: G01R27/02
Filed: 1992-10-07
Abstract: An apparatus for identifying and measuring in real time substances overlying a surface comprises a plurality of electrodes, a temperature sensor, an electrode control system connected to the plurality of electrodes for defining an electric field, an amplitude and phase measurement system connected to the plurality of electrodes and to the electrode control system for measuring a plurality of currents responsive to the electric field and converting the currents to a measurement set and computer for storing a map comprising a partition of a vector space of predetermined characteristics of substances into regions of profiles corresponding to the substances which could be overlying the surface. The computer correlates the measurement set with the map thereby identifying and quantifying the substances overlying the surface and generates an output signal corresponding to the identity and quantity of substances overlying the surface. A display responsive to the output signal displays the identity and quantity of substances overlying the surface.

Title: Method and apparatus for computer code processing in a code translator
Inventor: BENSON THOMAS R
IPC: G06F11/28
Filed: 1992-03-04
Abstract: A code translator, constructed similar to a compiler, accepts as an input to be translated the assembly code written for one architecture (e.g., VAX), and produces as an output object code for a different machine architecture (e.g., RISC). The input code is converted into an intermediate language, and a flow graph is constructed. The flow graph is referenced by a flow analyzer for recognizing certain architecture-specific and calling standard-specific coding pratices or idioms that cannot be automatically converted, particularly relating to stack usage, register usage, condition codes, and passing arguments for procedure calls. By tracking stack usage within routines, the compiler can distinguish up-level stack and return address references from valid local references.  Also, it can inform the user of stack misalignment, which has a severe performance penalty, and can detect code segments where different flow paths may result in different stack depths at runtime, which may indicated a source code error. Register usage is likewise tracked to determine which registers are destroyed by a routine, and generate routine prologue and epilogue code which performs register saves, as well as provide register "hints" to aid the user in adding an entry point declaration or documentation for the routine. The usage of condition codes is likewise tracked, by a backward walk through the flow graph, so that code to fabricate needed values is generated. In addition, all argument pointer base memory references in the input code is tracked to determine how the same argument reference may be made in the target environment.

Title: Sleeve for increasing retention value of a screw
Inventor: LEIBHARD ERICH
IPC: E01B9/14
Filed: 1992-12-04
Abstract: The retention value of a screw previously inserted into a wooden railroad tie is increased by an axially extending sleeve (20) having an external thread (24) and an internal thread (25). The thread revolutions of the internal thread (25) are offset axially by half (h) the thread pitch (H) of the external thread (24). due to this offset of the threads, the screw is positioned in the sleeve so that its threads are located between the external thread revolutions affording a new retention, while the external thread (24) seats within the thread previously formed in the wooden railroad tie by the screw.
Patent CA-2084720-A1 (CA)
Inventor: EVANS JAMES G
IPC: H04M1/733
Filed: 1992-12-07
Abstract: A cordless telephone system is arranged for extending the operating range of a cordless telephone portable unit within such system.  The cordless telephone system comprises a plurality of cordless telephone stations that plug into any available wall telephone jack and may share the intrapremises telephone wire-pair with one or more existing corded telephone stations without interference. Each cordless telephone station consists of a cordless telephone base unit and its associated cordless telephone portable unit.  Although each of the portable units is associated with a particular base unit, all of the portable units are able to operate with any of the base units in the system.  As a user of a portable unit with a call in progress roams about a premises, all base units monitor the quality of the radiofrequency signal received from the portable unit.  If the signal quality of a base unit actively communicating with the portable unit deteriorates to below an acceptable level, control apparatus in the system identifies another base unit and executes a hand-off of the communication link with the portable unit to this base unit that is then receiving the signal from the handset unit with an acceptable signal quality. Operational control for the base units is provided through a time division multiple access arrangement wherein a communications channel is imposed on the existing premises telephone wire-pair above the audio frequency band used for standard telephone service.

Title: Uplink null intrusion rejection for satellite communications systems
Inventor: PROFERA CHARLES E JR
IPC: H04B15/00
Filed: 1993-02-11
Abstract: A satellite communications system includes a feed array and reflector receiving antenna coupled to a dual-mode network, for generating two channels, with independent signals representing two beams, one for each channel. Each output channel of the dual-mode network contains redundant information relating to a plurality of information channels. In the absence of an interfering signal or intrusion, the combined signals are amplified and block frequency-converted, then de-multiplexed into separate channels, which are each applied through selection switches to a transmitter multiplexes for retransmission. An alternate signal is tapped from each of the two received signal channels, phase controlled, and combined, to produce a combined signal representing a receive antenna beam with a null controllable in position in response to phase. The combined signal is demultiplexed into separate information channels. In the presence of an intrusion in one of the channels, the selection switch for that channel is set to an alternate position, in which the alternate signal is selected for transmission. Since the alternate signal includes a null in the receive beam, the position of the null may be set to the location of the intrusion signal to suppress the signal.

Abstract: ABSTRACT                    COSMETIC COMPOSITION      A composition for topical application to human hair or skin contains a chemical analogue of dihydroxyphenyl alanine (DOPA).  This chemical analogue can be absorbed by skin or by a hair follicle and metabolised in-vivo, thus leading to the formation of melanin in skin or to the growth of melanin-pigmented hair.  Consequently the composition can give controlled skin darkening to mimic sun-induced tanning or can bring about the growth of dar hair in place of the grey or white hair.
