Abstract: In various embodiments, a High Definition (HD) camera may be controlled by one or more motors in a base of the HD camera. Cables and other components may be used to manipulate the camera lens through the side arms of the HD camera. Putting the motors in the base may reduce the size of the outer case of the HD camera and add stability. In some embodiments, images from the HD camera may be converted into a serialized stream and transported over a cable from the lens through a center shaft of the HD camera. Other components may also be used to increase the functionality of the HD camera. In some embodiments, a camera support mechanism may be provided to couple a camera to a display. The camera support mechanism may include a front lip and rear leg to hold camera in place.

Abstract: Systems and methods are described which utilize a recursive security protocol for the protection of digital data. These may include encrypting a bit stream with a first encryption algorithm and associating a first decryption algorithm with the encrypted bit stream. The resulting bit stream may then be encrypted with a second encryption algorithm to yield a second bit stream. This second bit stream is then associated with a second decryption algorithm. This second bit stream can then be decrypted by an intended recipient using associated keys.

Abstract: A high quality stereophonic sound enclosure system high resolution intended for computer visual display monitors employing cathode ray tubes (CRTs) having a vertical aperture grill, and methods for construction of same. The aperture grill has a natural frequency centered within the musical scale. The stereo speaker system comprises a ported speaker enclosure within which are mounted two conventional cone speaker assemblies. A stereo audio amplifier and control unit for controlling the audio signals delivered to the speakers is mounted within the speaker enclosure. The speaker enclosure is internally mounted within the monitor with a minimum number of attachment members incorporating vibration isolation material to remove vibration components near the natural frequency of the aperture grill. The speaker enclosure is internally reinforced to reduce structural deformations which contribute to airborne transmitted vibration within the monitor housing when the speaker system is operating.

Abstract: A method and apparatus for processing digital audio data comprises remapping channel status information in an input digital audio bit stream into a uniform format. The channel status information in the uniform format contains a super-set of data included in the channel status block of the original data and comprises a “higher level” form of presentation than the original status information, thereby reducing the amount of processing required by the application program in interpreting the audio data. The translation of audio data between different formats is performed in an interface unit. The interface unit strips the channel status information from the incoming digital audio data, translates the channel status information into a desired form, and then presents the audio data and the translated channel status information to a host computer for further processing or storage. The translation and routing functions performed by the interface unit are controlled by data stored in one or more registers.

Abstract: A directional microphone intended for use in a computer visual display monitor, and methods for construction of same. The integral directional microphone assembly comprises a cardioid electret microphone capsule retained therein by acoustically transparent foam. The microphone housing is mounted internally within a display monitor housing facing the user and adjacent to the top surface of the monitor housing. The microphone housing comprises a frontal opening and a plurality of nonfrontally facing openings which together maximally preserve sound pressure gradient applied to the microphone capsule, resulting in a hypercardioid spatial response.

Abstract: Manual actuation of a stop/eject button on a computer causes a signal to be sent to both the computer's operating system and to a wireless communication controller. The operating system interprets this signal in a manner analogous to a conventional signal to open the drawer, or door, of a compact disk drive device when a compact disk is not currently present in the drive device. If a compact disk is present in the device, the operating system ignores the signal. In this case, the communications controller operates in a normal fashion to interrupt access to the compact disk, instruct the operating system to unmount the disk, and thereafter eject the disk by opening the drive door.

Abstract: The audio system having a master clock, a serial port clocked according to a serial clock from the audio system, a programmable audio functional circuitry programmable and operable at a plurality of sample rates, and a rate selection control logic which sense a ratio between the serial clock and the master clock. The serial clock is derived from the master clock. The rate selection control logic reprograms the audio functional circuitry based on the ratio, to operate at one of the plurality of sample rates in response to a change in the clock rate of the serial clock, such that the audio functional circuitry operates at another of the plurality of sample rates.

Abstract: A protocol for transferring audio data and control/status data between audio functional units. The protocol involves multiplexing the audio data and control/status data. The multiplexed data is then transferred between a first audio unit and a second audio unit on two wires, each corresponding to the direction of data flow, and according to a clock and a synchronization pattern on third and fourth wires respectively.
