Publication number: 20110210818Abstract: A mobile electronic control device, such as an electronic key, is used to access or otherwise control the operations of a field device, such as an appliance, power tool, shipping container, etc. In a control event in which the mobile control device interacts with the field device via wired or wireless communications, the control device obtains the current location and the field device ID. The communications between the mobile control device and the field device may be secured with encryption. The location information is used by the mobile control device to determine whether the field device should be accessed or enabled. Alternatively, the location information may be stored separately in a location sensing device, and the control event data recorded by the key and the location information recorded by the location sensing device are later combined when they are downloaded into a management system for auditing. Moreover, an electronic access control device is disclosed comprising two microprocessors.Type: ApplicationFiled: April 14, 2011Publication date: September 1, 2011Inventors: William D.

Patent number: 7821395Abstract: A vending machine uses a field-programmable electronic lock that learns a key code from a corresponding electronic key, a hand-held program unit, or an external computing device via wireless communications. In one mode, the electronic lock has a learning process activation device that is accessible only when the door of the vending machine is in the open position. In another mode, the electronic lock is programmed in the field without first opening the vending machine. A program command and access control data including a new access code are transmitted wirelessly from a hand-held program unit or the like. Alternatively, an external computing device is used to program the electronic lock via long-range wireless communications, and an electronic key is then used to open the electronic lock to physically access the vending machine.Type: GrantFiled: May 4, 2004Date of Patent: October 26, 2010Assignee: Micro Enhanced Technology, Inc.Inventors: William D.

Patent number: 7741952Abstract: An electronic lock utilizes two microprocessors remote from each other for enhanced security. The first microprocessor is disposed close to an input device such as a keypad, and the second microprocessor is disposed close to the lock mechanism and well protected from external access. The first microprocessor transmits a communication code to the second microprocessor when it receives via the input device an access code that matches a preset access code. The second microprocessor opens the lock if the transmitted communication code matches a preset communication code. The dual-microprocessor arrangement is advantageously used in a voice controlled access control system and in a motorcycle ignition control system. The present invention further provides an electronic access control system which has a master electronic key having a preset number of access, and an electronic alarm system for a bicycle that has a remote control mounted in the helmet of the rider.Type: GrantFiled: February 21, 2007Date of Patent: June 22, 2010Assignee: Micro Enhanced Technology, Inc.Inventors: William D.

Patent number: 7495543Abstract: A vending machine uses a field-programmable electronic lock that learns a key code from a corresponding electronic key. The electronic lock has a learning process activation device that is accessible when the door of the vending machine is in the open position. Using the learning process activation device, a service person activates the electronic lock to perform a key code learning operation, in which the electronic lock receives a key code transmitted from an electronic key and stores the key code in a non-volatile memory for future access control of the vending machine. Data encryption is employed in the communications between the key and the lock to ensure the security of the communications. A communication device installed in the vending machine for communicating with a home base computer allows the operation of the electronic lock to be remotely controlled for access control and auditing purposes.Type: GrantFiled: November 24, 2004Date of Patent: February 24, 2009Assignee: Micro Enhanced Technology, Inc.Inventors: William D.

Patent number: 6923155Abstract: An accurate method of determining the power developed by selected cylinders of a multiple cylinder engine is based on the concept of controlling engine rpm for test purposes by adjusting the load on the engine instead of controlling speed by adjusting the fuel rate as is commonly done in normal engine operation. The method may be utilized for evaluating cylinder performance and for accurately balancing the output of the individual cylinders. It is particularly useful in railroad applications where the engine operates a generator that produces electric power and the system is provided with dynamic braking grids, which can be utilized as resistor grids for load testing the engine. However, the method is also applicable to other engines and other engine arrangements where engine power may be absorbed by a generator or dynamometer for controlling the load for test purposes.Type: GrantFiled: April 23, 2002Date of Patent: August 2, 2005Assignee: Electro-Motive Diesel, Inc.Inventors: Paul Gottemoller, Keith E.

Patent number: 6814060Abstract: A diesel engine emission control system which optimizes fuel injection timing over a range of air temperatures, air pressures, and engine air flow rates. The emission control system includes a control module interfacing with a fuel injection timing module which in turn interfaces with an engine fuel injection system having fuel injectors. The control module receives data from an air temperature sensor, an air pressure sensor, and an engine boost pressure sensor. The control module determines air density and the air flow rate through the engine to determine optimal fuel injection timing. The injection timing information is relayed to the injection timing module which alters the timing of the fuel injectors to operate the engine at a maximum efficiency possible within applicable emission regulation limits.Type: GrantFiled: September 26, 2003Date of Patent: November 9, 2004Assignee: General Motors CorporationInventors: Keith E.
