Abstract: An apparatus for use with an electronic device having a microphone and a camera. The apparatus comprises a structure configured to detachably couple to the device, and a shutter supported by the structure and comprising a lens shutter configured to obscure a lens of the camera when in an engaged position. A generator is supported by the structure and configured to generate a force that acts on the microphone and renders the microphone unresponsive to voice sounds.

Abstract: A mobile communications device includes a display, one or more sources comprising at least one microphone and at least one camera, a wireless communications module, a main processor, and a secured processor inaccessible by the main processor. A housing supports components of the device and is configured for hand-held manipulation. A shutter is supported by the housing, and comprises a lens shutter situated within the housing and configured to obscure a lens of the at least one camera when activated. A user actuatable switch is coupled to at least the one or more sources, the main processor, the secured processor, and the shutter. The switch is configured to selectively activate and deactivate the lens shutter. The switch is also configured to divert signals produced by the sources away from the main processor when activated, and couple signals produced by the sources to the main processor when deactivated.

Abstract: A series of scans is generated for a subsurface and a derivative image is created using the series of subsurface images. One or more tests are performed on the derivative image, and a subsurface object is detected based on the one or more tests. A sensor is configured to generate a series of scans for a subsurface and a processor is coupled to the sensor. The processor is configured to execute stored program instructions that cause the processor to generate a series of images of the subsurface using the series of scans, create a derivative image using the series of subsurface images, perform one or more tests on the derivative image, and detect a subsurface object based on the one or more tests.

Abstract: An optoelectronic pickup for a musical instrument includes at least one light source which directs light to impinge a sound generating element of the musical instrument in at least one photoreceiver located to detect the reflected light, so as to generate an electrical signal that is responsive to sound generating element movement.

Abstract: A touch sensor is configured to sense a contact event occurring between a body part of a user and the touch sensor. The touch sensor is configured to produce contact data in response to the sensed contact event. A processor is coupled to the touch sensor and memory. The processor is configured to store in the memory a sequence of data frames each comprising contact data associated with a different portion of the user's body part. The processor is further configured to generate biometric signature data using the sequence of data frames.
