Patent number: 8149102Abstract: An interface is provided that configures itself dynamically based on sensor information received from a sensor assembly or actuator information received from an actuator assembly. The interface may be configured to interoperate with sensor assemblies including analog transducers, smart transducers providing digital outputs and various actuators. The sensor information or the actuator information may include information for managing power consumption associated with the operation of the sensor or the actuator. Using the sensor information or the actuator information, a power management scheme may be implemented to reduce power consumption and extend the operational time of a module. The sensor information also includes information about the sensor signal generated by the sensor. The information about the sensor signal allows the module to interoperate with more diverse types of sensors.Type: GrantFiled: March 25, 2009Date of Patent: April 3, 2012Assignee: Memsic Transducer Systems Co., Ltd.Inventors: Matthew Miller, Alan S.

Patent number: 8144197Abstract: A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of proximity of objects. A central computer accumulates the data produced or received and relayed by each module for analyzing proximity responses to transmit through the adaptive network control signals to a selectively-addressed module to respond to computer analyses of the data accumulated from modules forming the adaptive network. Interactions of local processors in modules that sense an intrusion determine the location and path of movements of the intruding object and control cameras in the modules to retrieve video images of the intruding object.Type: GrantFiled: June 13, 2005Date of Patent: March 27, 2012Assignee: Memsic Transducer Systems Co., LtdInventor: Alan S.

Patent number: 8005108Abstract: A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of physical properties sensed at the modules. A new module is joined in the adaptive network in an expedient manner. The new module transmits a burst of beacon messages after the interactive module is activated to discover neighboring interactive modules deployed and operating in the adaptive network. The neighboring interactive module stays in a sleep-mode of low-power expenditure. The beacon messages persist for a first interval longer than a second interval during which the neighboring interactive modules remain in the sleep mode. After receiving the beacon messages, one or more neighboring interactive modules transmit response messages to the new interactive module. The new interactive module receives the response messages and selects a neighboring interactive module for communication based on the received response messages.Type: GrantFiled: October 31, 2007Date of Patent: August 23, 2011Assignee: Memsic Transducer Systems Co., Ltd.Inventors: Alan S Broad, Ning Xu

Patent number: 7369047Abstract: A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of radio-frequency identification signals, and indicative of proximity sensing at the module. A central computer accumulates the data produced or received and relayed by each module for analyzing inventory, pricing and customer responses to transmit through the adaptive network signals representative of information to be displayed at selectively-addresses modules in response to computer analyses of the data accumulated from modules forming an adaptive network.Type: GrantFiled: March 30, 2005Date of Patent: May 6, 2008Assignee: Crossbow Technology, Inc.Inventors: Alan S.

Patent number: 7176808Abstract: A method and system updates a network of sensors remotely through the use of a communication link. The sensors to be updated as well as data files to perform the updating are selected at a base station. The selected sensors are notified of the upcoming update by the base station and may accept or reject the update. The sensors that approve the update then receive data files through the communication link. The sensors notify the base station of any missing data files, which are then retransmitted to all sensors that may be missing data files from the first transmission. After the sensors receive all data files, the update is initiated.Type: GrantFiled: November 11, 2003Date of Patent: February 13, 2007Assignee: Crossbow Technology, Inc.Inventors: Alan S.
