Patent CA-2239897-A1 (CA)
Inventor: HARDT RAINER
IPC: A47G33/12
Filed: 1996-12-06
Abstract: The invention concerns a device for clamping the trunk of a Christmas tree or the like, the device comprising a stand having at least three clamping jaws (5) which are disposed in a base plate (1) having an opening (2) for receiving the trunk, are distributed about the opening (2), and can be moved in order to clamp the trunk in the opening (2). In order to adapt the clamping jaws (5) easily to the cross-section of the trunk, secure the latter reliably with a small stroke and be able to release or cancel the clamping effect easily, the base plate (1) is associated with a closure device which can move in two opposite directions. In one direction, the closure moves the clamping jaws (5) out of the opening (2) and, in the other direction, it first releases the clamping jaws (5) so that they can move into abutment on the trunk and then urges the clamping jaws (5) against the trunk with the necessary degree of clamping force.

Title: Laser a guide d'ondes excite par hf
Inventor: MUELLER ERIC R
IPC: H01S3/038
Filed: 1998-03-13
Abstract: L'invention concerne un dispositif de blocage (23) destiné à un laser excité par HF, qui permet de réduire la contrainte exercée sur des composants céramiques (28), et qui est en outre moins onéreux que des dispositifs actuels de blocage. Dans le laser excité par HF, il manque une électrode sur les zones d'intersection de canaux de guide d'ondes (39). Des couvercles en céramique (48) sont prévus sur une partie de ces zones d'intersection de canaux (39) afin de réduire l'accumulation de plasma. La tête à composant optique (55) utilise des forces de compression radiales pour maintenir le composant optique contre un support (54), ce qui permet d'empêcher une distorsion de la face du composant optique. Le canal de guide d'ondes (37) du laser excité par HF présente une section transversale en forme de U et un rapport d'aspect supérieur à un sur un, ce qui permet d'améliorer la performance du laser. Un dispositif (88) de réorientation de faisceau permet à la tête laser de servir de surface de montage pour d'autres composants optiques. Des orifices ou fentes de décharge sont prévu(e)s dans le guide d'onde (36) pour décharger l'accumulation de pression dans les canaux (37) du guide d'onde (36).

Title: A voice transmitting apparatus, a voice transmitting method, and a voice band signal transmitting system using the same apparatus or the same method
Inventor: KAWANOBE TAKESHI
IPC: H04L47/43
Filed: 1998-11-10
Abstract: A voice band signal is compression-encoded at a voice compression-encoding portion and is assembled into a cell at a cell assembling portion. Conversely, the voice band signal is disassembled at a cell disassembling portion and is decoded at a voice compression-decoding portion.  When, from both of up and down data judging portions, receiving a judgement of coincidence of the voice band signal with a signal at the time when the line is unused, a timer counts a continuation time.  When the continuation time exceeds a protection time, a protection time judging portion causes the cell assembling portion to stop the cell transmission.  When, from either of the up and down data judging portions, receiving a judgement of no coincidence with the signal at the time when the line is unused, or when the continuation time does not exceed the protection time, the cell assembling portion is directed to transmit the cell.

Inventor: CLOUTIER MARK MILES
IPC: H03L7/18
Filed: 1999-01-27
Abstract: Disclosed is a frequency-locked loop (FLL), which attempts to bring about frequency and phase synchronization between two signals over the control bandwidth of the loop: a reference signal and a voltage-controlled oscillator (VCO) signal. A preferred embodiment of the invention employs a reference signal generated by a crystal oscillator of frequency f REF  (possibly reduced in frequency by dividing by a factor R), and a VCO signal generated by the oscillations of an unquenched SRG resonator (possibly passed through a limiting amplifier) with tunable resonant frequency f RES (possibly reduced in frequency by dividing by a factor N). These (possibly divided-down) signals are connected to the inputs of a phase/frequency detector (PFD). A PFD a circuit which compares the phases of two digital input signals, denoted "R" and "V" for "reference"  and "VCO"; if a reference rising edge precedes a VCO rising edge, an "up" pulse denoted "U" is generated, while a VCO edge preceding a reference edge generates a "down" ("D") pulse. These pulses are used to control the current sources in a charge-pump circuit whose net current is applied to a loop filter (LF) which creates a voltage using some kind of charge-storage element. This loop filter voltage is a so-called error voltage whose value is used to control the frequency of the resonator;  the combination of PFD, charge pump, and LF is connected such that the error voltage is controlled to bring the reference signal and VCO signal into phase synchrony.

Inventor: LITVINOVITCH SERGUEI
IPC: G01N21/19
Filed: 1997-11-05
Abstract: The present invention provides a new analysis based on Differential Spectral Topographic Analysis (DISTA). Using data from the spectral methods known in the art, DISTA is based upon the normalization of the spectra to a fixed topographic space, creating a set of spectral forms, and the summation of the absolute differences in topography between one or more reference spectra and the test spectra taken at different magnitudes of the perturbing parameter. This method allows for a sensitive estimate of the fraction of form A and form B of an entity of interest. This method also allows for the calculation of apparent free energy from the conversion of the entity of interest from a first to a second form where appropriate, and in the alternative, calculation of a fraction of structural changes.

Title: Infrared blaster control system in cable television communication systems
Inventor: MICHAUD TED RICHARD
IPC: H04N5/782
Filed: 1997-11-19
Abstract: A system for delivering selective VCR control codes to programmable settop terminals (20) over a CATV communication system (22) includes a headend (12) for storing and transmitting VCR control code information to the settop terminals and a plurality of settop terminals for receiving the control codes.  The CATV communication system delivers the VCR control codes to individual subscribers within the vertical blanking interval of one of the broadcast channels or over a control datachannel. A set-up procedure is required for each VCR to determine the appropriate set of VCR control codes. Upon determining the specific type of VCR the subscriber has, the VCR control codes transmitted through the CATV system are stored in the settop terminal in non-volatile memory. Since the settop terminal only stores the VCR control codes for a single type of VCR, memory requirements are minimized.
