Title: Pressure sensor membrane having stepped annular peripheral surfaces and sensor employing same
Inventor: HELLER HEINZ
IPC: G01L7/08
Filed: 1997-12-09
Abstract: The invention concerns a membrane for a pressure sensor. The membrane has, on a flat central face, an annular attachment face, which is disposed concentric to the central face, and a non-flat connecting face, which links the central face with the edge face.  The connecting face is formed from at least one annular step, which consists of one flat annular face and one truncated-cone-shaped step face, which connects radially inward to the annular face. The annular faces and the central face lie in planes parallel to each other, whereby the heights of the step faces measured perpendicular to the plane of the central face are very small in relationship to the width of the respective step. This stepped design of the membrane results in a high linearity of the characteristic of the membrane pressure sensor and to a steep slope of the characteristic in its linear region.

Patent CA-2228234-A1 (CA)
Inventor: DIAMOND SIDNEY
IPC: B65D83/04
Filed: 1998-01-28
Abstract: A portable gumball dispenser has a reservoir mounted atop a pedestal formed of a nested assembly of concentric tubular members and a base. When offset apertures in top walls of the tubular members are in register with each other and with an opening in the bottom of the reservoir to permit a single gumball to drop into a dispensing chamber within the pedestal, apertures in the side walls are out of register to retain the gumball. Rotation of the tubular members to register the side wallapertures rotates the top wall apertures out of register to block any further gumballs dropping from the reservoir. A directional channel in the base facilitates a gumball rolling out when the side wall apertures in register. A cooperating annular ridge on the outside of the inner tubular member and an annular groove on the outer tubular member retain the tubular members in nested assembly. Extending upwardly from the inner tubular member is a bead which cooperates with an arcuate groove in the outer tubular member to provide respective rotational stops for the register of the top wall apertures and the side wall apertures.

Title: Method for admitting new connections based on usage priorities in a multiple access system for communications networks
Inventor: CHUAH MOOI CHOO
IPC: H04L12/56
Filed: 1998-10-08
Abstract: In a method for controlling admission of remote hosts to a base station in a wireless communications network based on usage priority, there are at least two user priority classes and the base station admits a threshold number of remote hosts of the lower priority class and a maximum total number of remote hosts. When a base station receives a connection request from a new user of the higher priority class, if the current total number of admitted users is less than the maximum allowable, the new user of class is admitted, otherwise, the base station checks to see if any lower priority class users are currently admitted and allow disconnection. If so, the base station disconnect the lower priority user and admits the new user. In one embodiment, the base station disconnects the "least recently used" admitted lower priority user that allows disconnection. If it is appropriate to disconnect lower priority users after they are admitted, then lower priority users are admitted as long as the total number of associated users is less than the maximum allowable admittedusers. If it is inappropriate to disconnect lower priority users after they are admitted, then lower priority users are admitted only if the number of admitted users is less than the maximum number of total admitted users and the number of lower priority admitted users is less than the maximum allowable admitted number. This approachcan be extended to multiple priority classes. In an alternate embodiment, lower priority class users are admitted if the total number of currently associated users of all classes is less than a second threshold, normally lower than the threshold for higher priority users, rather than being based partially (as a second threshold) on the number of currently associated users of that lower priority class.
