Patent number: 9160392Abstract: Control for a portable communication device (300) includes a control knob (304) which has an outer shell (610, 610a) at least partially formed of a dielectric material. The control knob is sized and shaped to facilitate fingertip control of the portable communication device, and has an integrated antenna (608, 608a) disposed within the outer shell. An axial member (612, 708) is provided on which the outer dielectric shell and the antenna are mounted to facilitate rotation of the control knob. A control device (606, 606a) is provided which is configured to control at least one electronic circuit (806) of a portable communication device responsive to a user rotation of the outer dielectric shell. The integrated antenna (608, 608a) is arranged to interface to at least one radio frequency communication circuit of a portable communication device.Type: GrantFiled: January 23, 2014Date of Patent: October 13, 2015Assignee: Harris CorporationInventors: Scott E.

Patent number: 9130316Abstract: A monitoring system for connector pins exposed to conductive/corrosive fluids and/or corrosive environments includes a first sensing portion having a pin monitoring section configured to measure a pin current flow of at least one conductor pin, and transfer a first signal. A second sensing portion produces a second signal indicating by a contactless determination the presence of a fastener providing physical connection between an interface member and a component. A decision logic device receives the first and second signals, compares the pin current flow to a predetermined range of values, and isolates electrical power to the conductor pin when the first signal indicates the pin current flow is outside the predetermined range of values. A sensor body created of a non-ferrous material and connected to the component includes a first insert member having the conductor pin and a second insert member defining a sensor sensing proximal presence of the fastener.Type: GrantFiled: October 5, 2012Date of Patent: September 8, 2015Assignee: HARRIS CORPORATIONInventors: Christopher D.

Patent number: 9065901Abstract: Modern electronic devices are becoming smaller while the need to critically locate acoustic sensors or transducers, e.g., microphones, is increasing in order to provide improved intelligibility in adverse environments. The acoustic transducers can be used in arrays with their outputs processed in beam forming and noise cancellation algorithms. The use and creation of features on the surface of a small package to deal with the problem of achieving high performance solutions in a limited space are disclosed herein. For example, embodiments of electronic communication devices (10) include acoustic transducers (26) integrated with other features such as a volume control (34, 50), an antenna (87, 260, 280), an adapter (300) which can be coupled to an input/output jack (90) and an accessory connector, or a projection (98).Type: GrantFiled: July 3, 2012Date of Patent: June 23, 2015Assignee: Harris CorporationInventors: Christopher D.

Patent number: 7937596Abstract: A method is provided for protecting embedded cryptographic processing circuits (112, 114), software and data, contained within electronic equipment. The method involves monitoring with a first processing device (210) embedded in the electronic equipment parameter values generated by sensors (108) provided in the electronic equipment. The method also involves evaluating with the first processing device each of the parameter values to determine if it falls within a predetermined range of acceptable values. The method further involves using a modified operating profile in the first processing device to perform the monitoring or evaluating step if one or more of the parameter values is determined not to be within the predetermined range. The method also involves selecting the operating profile to include defined variables selected from the group consisting of the predetermined ranges of acceptable values, the parameter values that are evaluated, and a rate at which the parameter values are evaluated.Type: GrantFiled: August 30, 2007Date of Patent: May 3, 2011Assignee: Harris CorporationInventors: Christopher D.
