Abstract: A cable tie, including: a head within which an opening is disposed; an elongated member fixed to the head; a plurality of teeth fixed to and disposed along at least a portion of a length of the elongated member; and a locking member disposed within and fixed to an inside surface of the head; wherein: a free end of the elongated member is tapered to a point; and the cable tie is configured for single-handed use in securing one or more objects. The cable tie provides easier and more efficient single-handed operation while enhancing the safety of cable ties in various applications.

Abstract: Various embodiments provide novel tools and techniques for position and/or motion tracking, including without limitation solutions that can be used for excavation and similar applications. In a particular aspect of some embodiments, a communication device with a camera may be provided to track the position and motion of a stick of an excavator or reference features located on a stick of an excavator. A location of a bucket of an excavator may then be calculated relative to the stick or reference features on the stick of the excavator. Thus, an operator of the excavator can use the communication device to effectively and efficiently track the location of the excavator bucket without the need for a second person to provide instructions about the location of the bucket.

Abstract: A method for distributing the QOS processing in a broadband access system to the system modems and the head-end equipment. Requests for a change in the operating parameters are transmitted on an exception basis, thereby greatly reducing the amount of system over-head required. In the upstream, the Cable Modem Termination System (CMTS) or Wireless Modem Termination System (WMTS or Wireless Hub) determines a signal-to-noise ratio (SNR) or Bit Error Rate (BER) (or similar measurable parameter) quality data for each received packet. If a measured parameter is outside of the predetermined limits, then the WMTS reports to the NMS (Network Management Operating System) the modem ID and the measured data of the particular packet. The NMS may then modify the operating parameters. In the downstream, each modem determines an SNR or BER (or some other measurable parameter) measurement for the incoming packets. These values may be compared to some boundary conditions.

Abstract: A method for correcting for the offset carrier frequency in a wireless modem is provided. The method further allows for the periodic correction of the offset of the carrier frequency. A Fine tuning method is implemented that uses fine tuning frequency increments to determine minimum and maximum edges of a received frequency from which to calculate an offset used to adjust the transmitted frequency or the receiver of the wireless modem. Power correction is performed for variances in received signal power by adjusting an output power relative to differences in received power compared to an expected received power value.

Abstract: A system and method for controlling a transverter from a wireless modem unit (WMU). A WMU delivers a control signal to a transceiver. This signal is outside the IF signal data range (preferably below 11 MHz). The signal is carried on the cable between the transceiver and the WMU. This signal is detected by the transceiver, and determines the timing and the control information. The signal is ASK modulated to enable low data rate transfer of messages between the WMU and the transceiver. The control signal is detected at the transverter using a detector circuit. Additionally, specific transverter detection circuits are disclosed to detect the control signal.

Abstract: A low cost redundancy scheme for the radio frequency front end of a wireless hub that requires a minimum number of down converters and upstream receivers to implement. The redundancy scheme may also be used as a back-up support for any upstream channel that is provided with a greater amount of data than the other upstream channels.

Abstract: A wireless modem contains a power inserter circuit along with the traditional modem components. The power inserter circuit isolates the modem components from DC power that is inserted on the coaxial cable to a transverter. One embodiment of the present invention provides for a wireless modem that contains separate power connections for the modem components and the transverter. Another embodiment of the present invention provides for one power connection for the wireless modem and a DC-to-DC converter for the modem component power. The power source is selected based on the power requirements of the transverter and the DC-to DC-converter converts the input voltage into the voltage level required by the modem components. By incorporating the power inserter within the modem enclosure, power cannot be accidentally inserted into the modem.
