IPC: A45F5/02
Filed: 1994-10-25
Abstract: An apparatus for holding various shapes and sizes of bottle openers and which itself is attached to the wearer's belt is described; which includes a roughly cone-shaped holster and a belt loop affixed thereto. The holster is approximately 2 inches in length and is cone-shaped with its top, wherein the bottle opener is inserted, being approximately 1 1/2 inches (long axis) by 1 inch (short axis). Its bottom is also open and is approximately 1 inch (long axis) by 3/4 inches (short axis).   The holster is composed of flexible elastic neoprene fabric, which is reinforced by a sewn ridge of neoprene along the top and bottom openings.   The bottle opener is inserted through the top of the holster with its handle emerging out the smaller bottom of the holster, which handle can then be grasped by the user and pulled down, thereby removing the entire opener through the bottom hole, which expands to allow the wider bottle-opener top to pass through it.   The neoprene fabric grips the bottle opener securely yet its expandability allows the same to be removed and reinserted quickly and repeatedly by the user, in one motion.   The holster is designed to be attached to the user's belt by way of a loop, alsomade from neoprene fabric, affixed to the holster by either a velcro mechanism or a button or a snap.   The present invention relates to an apparatus for a user's holding to his or her body various shapes and sizes of bottle openers, which can be removed and reinserted into the apparatus quickly and repeatedly.

Title: Low power, addressable data communication device and method
Inventor: ALLEN STEVEN P
IPC: H04W52/02
Filed: 1994-11-15
Abstract: An electronic tag (10) receives a data message (18) that has a wake-up section (20) followed by a session section (22).  The interrogation signal which carries the data message encodes the wake-up section (20) differently from the session section (22).  A power manager (28) decodes the wake-up section (20) using a very low power decoder (34) that remains energized during a standby state.  When the power manager (28) detects a predetermined identification code (26), it controls a switching circuit (32) to energize a controller (30).  The controller (30) may then decode, process, and respond to information conveyed during the session section (22).  If the power manager (28) does not detect the identification code (26), the controller (30) remains de-energized.  The power manager (28) also includes a synchronizer (38) which determines when a preamble (24) is detected, and an ID decoder (40) that determines when the wake-up section (20) conveys the predetermined identification code (26).

Title: Soil compaction
Inventor: BERRANGE AUBREY RALPH
IPC: E01C19/26
Filed: 1994-05-17
Abstract: Compaction of a soil surface is achieved by means of a machine (10) which has a movable, wheeled carriage (20) and an impact roller coupled resiliently to the carriage so as to move together with the carriage. The impact roller has one or more out-of-round compactor masses (12) designed to apply periodic impact blows to the soil surface (36). A soil working implement, in the form of an upright scraper blade (44) is carried by the carriage in a position trailing the impact roller. The function of the blade is to shape soil into the localised indentations (40) that are formed in the soil surface by the periodic impact blows applied by the compactor mass or masses. This smoothes out the soil surface for subsequent passes and reduces the shock loading on the tractive vehicle which pulls the carriage.

IPC: C01B3/40
Filed: 1995-02-17
Abstract: A hydrocarbon reforming catalyst material comprising a catalyst support impregnated with catalyst is provided for reforming hydrocarbon fuel gases in anelectrochemical generator. Elongated electrochemical cells convert the fuel to electrical power in the presence of an oxidant, after which the spent fuel is recirculated and combined with a fresh hydrocarbon feed fuel forming the reformable gas mixture which is fed to a reforming chamber containing a reforming catalyst material, where the reforming catalyst material includes discrete passageways integrally formed along the length of the catalyst support in the direction of reformable gas flow. The spent fuel and/or combusted exhaust gases discharged from the generator chamber transfer heat to the catalyst support, which in turn transfers heat to the reformable gas and to the catalyst, preferably via a number of discrete passageways disposed adjacent one another in the reforming catalyst support. The passageways can be slots extending inwardly from an outer surface of the support body, which slots are partly defined by an exterior confining wall. According to a preferred embodiment, the catalyst support is non-rigid, porous, fibrous alumina wherein the fibers are substantially unsintered and compressible, and the reforming catalyst support is impregnated at least in the discrete passageways with Ni and MgO, and has a number of internal slot passageways for reformable gas, the slot passageways being partly closed by a containing outer wall.

Patent CA-2153153-A1 (CA)
Inventor: BESSE PIERRE-ANDRE
IPC: H04B10/29
Filed: 1994-10-18
Abstract: L'invention concerne le domaine de l'optique intégrée et la technologie des communications. Dans ce domaine, des mélangeurs et des diviseurs de faisceaux compacts intégrés jouent un rôle important. Les fonctions optiques assurées par de tels dispositifs peuvent être remplies par des coupleurs multimodes à interférences. Avec ces coupleurs, un certain nombre d'entrées est uniformément réparti sur toutes les sorties. Ces composants sont soumis à de larges tolérances de fabrication et ne subissent pas l'influence de la polarisation lorsque l'approximation est bonne. Dans les coupleurs multimodes à interférences classiques pourvus de flancs parallèles, les répartitions de phase et d'intensité à la sortie sont fixes. Cependant, dans de nombreux cas d'utilisation, il est nécessaire de pouvoir influer sur ces répartitions de façon contrôlée. L'invention concerne un procédé permettant de modifier, de manière contrôlée, les rapports de phase et d'intensité à la sortie de coupleurs multimodes à interférences. A cet effet, les coupleurs multimodes à interférences classiques sont d'abord divisés en deux parties. Chaque partie est ensuite transformée séparément de façon que les propriétés d'auto-formation d'image soient maintenues. Enfin, les parties séparées sont de nouveau montées en série. Un choix judicieux des transformations permet d'obtenir différents diviseurs de faisceaux et mélangeurs contrôlés. Les rapports sont changés par un simple contrôle à large tolérance de paramètres géométriques.
Patent CA-2153729-A1 (CA)
Inventor: NISHIDA TOSHIO
IPC: H04Q3/58
Filed: 1995-07-12
Abstract: A large amount of control information is transmitted at high speed to a telephone terminal without changing the transfer capacity of a current control channel. When a call is terminated by any of the extension terminals, the extension terminal sends, for example, a lamp control signal to a extension terminal via D channel thereafter, if a large amount of display control signals are to be transmitted to the extension terminal, after sending the display control signal to the extension line, a central controller causes the extension line to send a B channel seizing signal to the extension terminal via D channel. This causes paths of the B channel(s) to be so changed that both the controllers within the extension line and the extension terminal are accessible to the B channel(s).  Subsequently, the extension line can transmit the display control signals at high speed to the extension terminal via B channel(s). Thus, the extension terminal displays on the display device the display control signals received through the B channel(s).

Filed: 1996-02-12
Abstract: A radio channel estimation method includes a combination of BER (bit error rate) estimation and RSSI (received signal strength indicator) estimation.  The RSSI and the BER are detected from a received signal through a radio channel, and then the radio channel is estimated based on the RSSI and the BER.  A quality of the radio channel is estimated to be degraded unless the BER meets a first criterion and the RSSI meets a second criterion.          The BER meets the first criterion when an average number of times during a time period that the BER exceeds a maximum value is smaller than a first threshold value.  The RSSI meets the second criterion when an average number of times during a time period that the RSSI is below a minimum value is smaller than a second threshold value.
