Patent number: 10514922Abstract: A microcontroller includes a program memory, data memory, central processing unit, at least one register module, a memory management unit, and a transport network. Instructions are executed in one clock cycle via an instruction word. The instruction word indicates the source module from which data is to be retrieved and the destination module to which data is to be stored. The address/data capability of an instruction word may be extended via a prefix module. If an operation is performed on the data, the source module or the destination module may perform the operation during the same clock cycle in which the data is transferred.Type: GrantFiled: February 27, 2017Date of Patent: December 24, 2019Assignee: Maxim Integrated Products, Inc.Inventors: Jeffrey D. Owens, Edward Tangkwai Ma, Donald W. Loomis, Thomas Augustus Chenot

Patent number: 6064316Abstract: An access control system, has at least one door to a secured area, each door having a strike plate, a host computer, at least one door control module coupled to the host computer, one door control module for every door; and at least one door reader coupled to the at least one door reader coupled to the door control module to activate the strike plate to release the door. The access control system further has at least one electro-mechanical key to independently actuate a lock that corresponds to the door(s). A master keying device to rekey the lock that corresponds to door(s). The host system records information selected from the group consisting of time of entry, place of entry, identification of entered party, and/or any combination thereof.Type: GrantFiled: March 5, 1998Date of Patent: May 16, 2000Assignee: Dallas Semiconductor CorporationInventors: Mark Glick, Nicholas M. G. Fekete, Michael L. Bolan, Jeffrey D. Owens

Patent number: 5848541Abstract: A retrofit door knob assembly is adapted to fit within an aperture in a door in place of a conventional mechanical lock assembly. The retrofit door knob assembly is similar in appearance to a conventional door handle assembly, but includes a motor coupled to a latch, and suitable electrical and mechanical key inserts for receiving separate electrical and mechanical keys. Either a mechanical or electrical key can operate the latch. The electrical key insert includes a data probe within the handle for receiving the electrical key and the electrical key is provided with a means for gripping to allow a user to turn the handle with the key after the latch is unlocked by the motor.Type: GrantFiled: November 29, 1994Date of Patent: December 15, 1998Assignee: Dallas Semiconductor CorporationInventors: Mark Glick, Nicholas M. G. Fekete, Michael L. Bolan, Jeffrey D. Owens

Patent number: 5823027Abstract: A retrofit electromechanical door knob assembly is adapted to fit within an aperture in a door in place of a conventional mechanical lock assembly. The retrofit door knob assembly is similar in appearance to a conventional door handle assembly, but includes a motor coupled to a latch, and suitable electrical and mechanical key inserts for receiving separate electrical and mechanical keys. Either a mechanical or an electrical key can unlock the latch. The electrical key insert includes a data probe within the handle for receiving the electrical key and a means for gripping an electronic key to allow a user to turn the handle with the key after the latch is unlocked by the motor, thereby withdrawing the latch.Type: GrantFiled: June 7, 1995Date of Patent: October 20, 1998Assignee: Dallas Semiconductor CorporationInventors: Mark M.

Patent number: 5749253Abstract: An access control system, comprises at least one door to a secured area, each door having a strike plate, a host computer. The access control system further comprises at least one electro-mechanical key to independently actuate a lock that corresponds to the door(s). The host system records information selected from the group consisting of time of entry, place of entry, identification of entered party, and/or any combination thereof. In addition, a door knob and mechanical locking mechanism selectively latches and unlatches the locking mechanism and can be actuated with a mechanical key; and circuitry to actuate the locking mechanism to selectively latch so that the door can open, the circuitry actuated by an electrical signal transmitted by an electrical key, the electrical signal communicated by an electrical contact extending through the mechanical locking mechanism. The circuitry is powered by a battery, which can be removed without disturbing or actuating unlocking mechanism.Type: GrantFiled: June 19, 1996Date of Patent: May 12, 1998Assignee: Dallas Semiconductor CorporationInventors: Mark Glick, Nicholas M.G.

Patent number: 4561963Abstract: A solid state electrode that includes a graphite core as both the internal reference and the electrical conductor that is preferably formed of graphite threads maintained as a bundle that in one embodiment, has an end thereof coated with a mixture of antimony and antimony oxide as a sensor element, the graphite junction forming the internal reference to that sensor element, and in another embodiment, the graphite core is wrapped tightly around a sensor formed from section or "shot" of a mixture antimony and antimony oxide, the graphite junction forming the internal reference thereto. The connected graphite core and antimony/antimony oxide sensor are then covered with an impermeable non-conductive plastic sheath, leaving a section of the antimony/antimony oxide sensor surface exposed, and the junction of that sheath to the antimony/antimony oxide sensor is preferably sealed as with an epoxy.Type: GrantFiled: July 30, 1984Date of Patent: December 31, 1985Assignee: Zinetics Medical Technology CorporationInventors: Jeffrey D. Owen, Harold M. Brown

Patent number: 4431508Abstract: A solid state graphite electrode to determine the activity of an ion-specie in solution. The graphite electrode of the present invention can be adapted for use as either an external reference electrode, an ion-selective electrode or as an internal reference electrode. The electrode includes, as an electrically conductive element, a supported section of graphite that is appropriately electrically connected through a potentiometer to show a difference in ion concentration as a voltage potential or emf. One graphite surface for immersion in a test solution is hydrophobized by coating it with a solution that contains an organic liquid molecule to covalently bond with hydroxyl groups (OH) of the graphite surface, rendering that surface hydrophobic. Preferably, the organic liquid is a silanizing agent, which coating after drying is covered with a hydrophobic layer or membrane that is preferably a polyvinylchloride (PVC) plastic.Type: GrantFiled: December 10, 1982Date of Patent: February 14, 1984Inventors: Harold M. Brown, Jr., Jeffrey D. Owen
