Patent number: 6977586Abstract: An article identification system relies upon correlating or “bonding” a detecting object with an identifying object on an auto-identification basis. Identification data is provided on an automated, high-reliability basis, without human control over the precise identification data that is transferred. On this basis a nursery infant-parent identifier system is provided whereby, when a detecting baby bracelet is brought into the presence of an identifying parent's tag, a reliable indication is provided as to whether the bracelet and tag have been previously bonded.Type: GrantFiled: February 13, 2001Date of Patent: December 20, 2005Assignee: Instantel IncInventors: Brian W. Martin, Jennifer A. Hartfield, Robert D. McCulloch

Patent number: 6727810Abstract: A method of detecting a variable number of objects within range of a receiver, is comprised of transmitting from each object a supervisory message from time to time, detecting the supervisory message by the receiver over a detection interval, and varying the detection interval based on a number of objects under supervision and the probability of collisions of the supervisory messages.Type: GrantFiled: October 12, 1999Date of Patent: April 27, 2004Assignee: Instantel, Inc.Inventors: Brian Martin, Jennifer McKenzie

Patent number: 5977877Abstract: A security tag having a strap for securing the tag to an object to be protected and an electronic module connected to the strap for detecting an attempt to defeat the tag by short circuiting and severing the strap. The strap is formed of plural discrete conductors connected to the electronic module, which conductors are insulated from each other at least along a substantial length of the strap. Short circuiting of opposite ends of a single pair of the conductors followed by severance of plural ones of the insulated conductors, or short circuit in between separate conductors can be detected by the electronic module as an alarm condition. Severance or misconnection of only one or a small number of the insulated conductors can be detected by the electronic module as not being an alarm condition.Type: GrantFiled: May 18, 1998Date of Patent: November 2, 1999Assignee: Instantel Inc.Inventors: Robert Donald McCulloch, David G. McEwing, Brian Wayne Martin, Jennifer Ann Hartfield McKenzie

Patent number: 5374921Abstract: A beacon is contained in a waterproof housing which is devoid of any electrical contact points. At a location at which a signal is to be applied to or received from the beacon, the housing is made sufficiently thin to allow light to pass therethrough. A light energy transmitter coupled to receive the signal to be transmitted into or out of the housing is located immediately adjacent or abutted against the translucent portion of the housing. A light energy receiver is similarly disposed adjacent or abutted against the other side of the housing, to receive the light energy. In this manner no electrical contacts need pass through the housing, and the beacon circuit is entirely protected by the waterproof housing, from water, soap, sweat, body oils, etc.Type: GrantFiled: November 13, 1991Date of Patent: December 20, 1994Assignee: Instantel Inc.Inventors: Brian W. Martin, Gary B. Loubert

Patent number: 5014040Abstract: A personal locator transmitter adapted to be worn on the wrist and having the size and appearance of a conventional wrist-watch. This transmitter is provided with a programmable memory, a transmitter controlled by the memory, an antenna for reliably radiating signals from the transmitter regardless of orientation of the wrist of a user and including both a manually operable alarm activated by pressing a button, and an automatic alarm actuated by an attempt to remove the unit from the wrist of the wearer. The unit is controlled by a control memory comprised of an EEPROM encoded with unique identification codes and other information as required in the specific application.Type: GrantFiled: October 16, 1989Date of Patent: May 7, 1991Assignee: Instantel Inc.Inventors: Philip W. Weaver, Kamal Fakhry, Shin Saito

Patent number: 4935748Abstract: A blast recorder and method for monitoring and processing vibrations from blasts, and for displaying the results in a nearly real time basis and in a manner which is easily interpreted by a relatively unskilled field worker and corresponds to a form which closely correspond to the real damage causing aspect of the blast than heretofore.Type: GrantFiled: May 15, 1989Date of Patent: June 19, 1990Assignee: Instantel Inc.Inventors: Rene Schmidt, Gary Loubert
