Title: Restraint garment
Inventor: ARGENTINO GIOVANNI
IPC: A41D13/00
Filed: 1997-01-14
Granted: 2000-05-16
Abstract: A restraint garment has a front body portion, permanently connected to a rear body portion, both extending from the neck of the patient down to the mid-height of the patient's thighs. The rear body portion has two detachable pieces connected to each other by a zip fastener. The garment also has first and second rear shoulder portions extending from the shoulder edges of the front body portion down to the bottom of the shoulder blades in the back of the patient, which are detachably connected to each other by another zip fastener. The bottom parts of the front and rear portions are detachably connected to each other by a third zip fastener extending continuously form one thigh to the other, thereby making it possible to completely open the garment at the patient's fork. Each of the zip fasteners are preferably locked either with a key-operated lock or with a buckle made of a snap fastener and a sliding sleeve. This restraint garment makes it difficult not to say impossible for a patient to undress. It is very difficult to remove and prevent the patientfrom having access to the covered part of his or her body. Moreover, this garment is easy to fit on a patient and gives easy access for the nursing staff to the diaper that the patient may wear and permits the patient to be secured to his or her bed or chair.

Abstract: A load coil device for a twisted pair telephone line is disclosed. The device is for compensating distributed stray capacitance in telephone lines that are longer the 18,000 feet. Typically, a load coil device would be inserted in the line every 6,000 feet. The device includes two windings, each winding to be connected in series with one of the conductors of the telephone line. The windings flatten the frequency response of the line in the voice frequency (VF) band. The device further has a capacitor connected in parallel across each winding. The values of the capacitors are chosen to provide a low impedance path that bypasses the windings for frequencies in the range of 20 kHz to 1.1 MHz. The device is particularly useful for long telephone lines over which high speed services such as asynchronous digital subscriber line (ADSL) are to be provided.

Abstract: An analysis processor applies an analysis process to input speech data thereby to obtain block lengths for respective attributes of voiced sound, voiceless sound and silence. A block data splitter splits the input speech data into blocks having the block lengths dependent on the respective attributes. A block data memory sequentially stores speech data split by the block data splitter as block speech data and the block lengths. A connection data generator generates connection data for connecting the adjacent block speech data each other at every moment by using the block speech data. A connection data storing portion sequentially stores the connection data. A connection order generator generates block connection order of the block speech data and the connection data at every moment according to at least the block lengths output sequentially from the block data storing portion and extension scaling factors in time for the respective attributes. A speech data connector connects sequentially the block speech data and the connection data based on the block connection order. Accordingly, the speed of output speech can be instantly changed in response to an instruction of an operator.

Abstract: Dans un réseau de communications, un utilisateur du réseau communique à l'aide d'une unité à distance (125) avec un autre utilisateur (30) via au moins une station de base (B¿1A?). Le réseau de communication possède une première station de base (B¿1A?) ayant une première zone de couverture et une seconde station de base (B¿2A?) ayant une seconde zone de couverture. Dans le cas où la communication n'est pas établie entre la seconde station de base (B¿2A?) et l'unité à distance (125), afin d'établir une communication entre l'unité à distance (125) et la première station de base (B¿1A?) lorsque l'unité à distance (125) se trouve dans la première zone de couverture et simultanément dans la seconde zone de couverture, la première station de base (B¿1A?) produit un premier signal de communication actif destiné à l'unité à distance (125). La première station de base transmet le premier signal de communciation actif à partir d'une première antenne (130). La station de base retarde le premier signal de communication actif afin de produire un premier signal de communication actif retardé et le transmet à partir d'une seconde antenne (135) ayant une certaine orientation par rapport à la première antenne (130) de sorte que le premier signal de communication actif et le premier signal de communication actif retardé s'affaiblissent indépendamment lorsqu'ils sont perçus par l'unité à distance. La première station de base (B¿1A?) peut mesurer un temps de transmission aller-retour du premier signal de communication actif afin d'identifier l'unité à distance (125) et s'assurer que cette dernière se trouve dans la seconde zone de couverture.

IPC: F16K7/14

Abstract: A liquid level monitor using a pressure actuated sensor to replace the open bubble tube. Air flows down the supply tube as in the bubbler, but rather than being released into the water, the air enters a chamber that has one movable wall, such as a diaphragm, that is acted on from the inside by pressurized air and from the outside by the hydrostatic head of the water. When the water pressure exceeds the chamber air pressure, the movable wall is pressed against an air outlet and does not allow air in the chamber to escape through the air outlet. One embodiment uses a diaphragm disposed over the air outlet; however, the concept may be extended to several other movable members, such as a piston with low actuation force. When the air chamber pressure exceeds the water pressure, the movable member moves away from the air outlet, releasing air and causing the chamber pressure to drop down to the water pressure.
