Patent CA-2275435-A1 (CA)
Inventor: BODOE JAN PETER
IPC: H01L23/12
Filed: 1997-12-19
Abstract: On réalise une structure de trou d'interconnexion en pratiquant un trou (3) par attaque chimique à travers un substrat (1) sur l'emplacement du trou d'interconnexion et en plaçant des lignes de transmission (25) sur les parois latérales inclinées ou en pente du trou (3). Ces lignes (25) continuent vers des conducteurs (17) situés sur l'autre surface du substrat (1) par l'intermédiaire de trous d'interconnexion (29) situés dans une partie libre d'une structure de couche mince du côté inférieur du substrat. Cette partie libre est résistante et fortement dimensionnée, ce qui permet d'y pratiquer plusieurs trous d'interconnexion (29) afin d'effectuer une connexion avec une pluralité de lignes parallèles (25) constituant, par exemple, une structure de bus. La partie libre fortement dimensionnée peut être, de plus, supportée par une couche de support épaisse (33) appliquée au sommet des couches dans le trou (3). L'application d'un plan de masse isolé (19) et d'une couche diélectrique (23) entre le substrat (1) et les lignes de transmission (25) permet d'adapter en impédance les lignes de transmission sur les parois latérales inclinées (8) de la structure de trou d'interconnexion. On peut créer sans difficultés ces parois latérales inclinées (8) du trou d'interconnexion par attaque chimique d'un substrat (1) en Si monocristallin afin d'obtenir une rainure en V. La structure obtenue de trou d'interconnexion est particulièrement bien adaptée pour des bus de transmission de données dont la densité de ligne de transmission n'a pas besoin d'être diminuée à travers la structure de trou d'interconnexion.

Title: Location dependent service for mobile telephones
Inventor: PETTIFOR JAMES DOUGLAS
IPC: H04M3/42
Filed: 1998-06-05
Abstract: A mobile telephone system provides a subscriber with services, for instance call barring and call forwarding, in dependence on the circumstances of the subscriber's mobile station. For instance, if the mobile station (1-9) has a first network (1) as its home network, the services provided are modified if it is detected that the mobile station (1-9) has registered with a second network (3). In particular, international calls may be barred when on the home network, but permitted when on the second network so that the user may call his home country. This is carried out by having a number of different service profiles stored in the home network (1-3) for controlling the interactions between the mobile telephone and the current network (1, 3), these service profiles being selected according to which network (1, 3) the mobile telephone (1-9) is currently working to.

Inventor: FUSINATO LYNN H
IPC: H04Q3/545
Filed: 1998-08-14
Abstract: A system and a method for managing calling name (CNAM) queries in a plurality of telephone networks (1-3) including a plurality of subscribers (10, 30, 50) each assigned a telephone number in a predetermined number series associated with a particular switch (12, 32, 52) in one of the telephone networks, wherein at least one of the number series is a portable number series including telephone numbers assigned by one network but connected to another network. According to the present invention (FIGs. 2A-B), if the calling party number (CgPN) belongs to a portable number series, gapping will be applied to CNAM queries containing either portable telephone numbers associated with a location routing number (LRN) identifying the switch and network to which the CgPN is connected, or non-portable telephone numbers belonging to the same number series as the LRN. On the other hand, if the CgPN does not belong to a portable number series, gapping will be applied to CNAM queries containing telephone numbers belonging to the same number series as the CgPN.

Abstract: The front door of most conventional ovens can become extremely hot to the touch. Children are typically attracted to appliances and can easily be burned from brushing by the appliance, or through direct contact with the appliance. While there are protectors from appliance dials and stove top burners, there are no known protective devices to prevent burns of this nature. This invention is for a cover made of fire retardant material (Solari insulation with Teflon outer cover) that would cover the oven door of most conventional ovens. Velcro tabs affixed to the sides of the oven door will hold it in place and an opening for the oven door handle will allow access to the oven. With the Child Proof Oven Door Cover, the outside front of the oven door will not be hot to the touch.

Patent CA-2302092-A1 (CA)
Inventor: YE MARK CHANGFENG
IPC: A44B13/00
Filed: 2000-03-24
Abstract: A first extension member has a head coupled to a first zipper head and a tail having a male connector and an elongated generally flat intermediate portion between the head and the male connector. A second extension member has a head coupled to a second zipper head and a body with a female connector that receives and locks the male connector and receives and permits free sliding movement of the elongated flat intermediate portion.      The female connector prevents removal of the male connector therefrom to prevent opening the zipper beyond a predetermined position based on the length of the elongated intermediate portion. Because the male connector is positioned generally at the end of the tail and the elongated intermediate portion is generally flat, the tail may slide freely within the female connector between the head and the male connector so that the zipper is therefore not locked in any fixed position.

Inventor: ZARETSKY ALBERT
IPC: H02H9/04
Filed: 2000-03-29
Abstract: A method for determining the extent of a transient's ability to cause MOV over heating and subsequent explosion by microprocessor analysis of an AC voltage input waveform with respect to a stored perfect sine wave. The microprocessor also calculates the RMS value of the applied voltage waveform and compares it to stored limits to determine if it could cause over heating of the MOV. In either case, the microprocessor will generate an out-of range signal to a disconnect device to take the MOV, and also the load, if desired, off line until normal line voltage is restored.

Patent CA-2309467-A1 (CA)
Title: Macrodiversity control system having macrodiversity mode based on operating category of wireless unit
Inventor: RAHMAN MOHAMED ANISUR
IPC: H04B7/04
Filed: 2000-05-25
Abstract: A macrodiversity control system provides a wireless unit with a macrodiversity mode depending on the operating category of the wireless unit. For example, a wireless communications system can have wireless units operating in categories related to the mobility of the wireless unit, such as fixed, limited fixed (mobility within the home cell) and/or fully mobile. For a wireless unit, the macrodiversity mode of the wireless unit can be established depending on the operating category for the wireless unit. Where the wireless unit is fixed and has good reception from a home base station, particularly in regions close to the home base station, macrodiversity for the wireless unit can be restricted. Because the mobility of the wireless unit is restricted in the fixed (or limited fixed) mode, the fading of signals between the home base station and the wireless unit should not be severe, thereby macrodiversity is disabled. Where the reception is poor, particularly in a region near the edge of the cell, the macrodiversity for the fixed (or limited fixed) wireless unit is enabled. The fixed (or limited fixed) wireless unit at the edge of the cell can benefit from macrodiversity, but because the wireless unit is fixed (or limited fixed), the fixed (or limited fixed) wireless unit is not handed off to another base station (or can only be handed off to a limited set of base stations).
