Patent number: 8468066Abstract: A network sensor system and protocol is provided. The network sensor system includes a sensor node that has a sensor for collecting high-resolution data, and a radio for transmitting that data to a central hub. The sensor node communicates to the hub with a wireless data link, and operators solely from a battery. Accordingly, the sensor node is autonomous, and has no wire connections, so may be discreetly and simply installed. The sensor node is normally operated in a power-saving sleep mode, and is minimally activated only for required periods of time. The sensor node may be activated responsive to a low power timer, or from another locally generated interrupt. The sensor node also implements power-saving transfer protocols to further reduce power needs. Many sensor nodes may be associated with a single central hub, and larger networked sensor systems may be arranged.Type: GrantFiled: August 29, 2007Date of Patent: June 18, 2013Assignee: AVAAK, Inc.Inventors: Bar-Giora Goldberg, Gioia Messinger

Patent number: 8390720Abstract: A system and method is provided for enabling an advanced optical magnification (zooming) function for low-power sensors, such as a remote wireless camera, using electronic methods and enabling that magnification be performed in any part of the imager. An image sensor has a set of imager pixels that have a defined field of view. A display device is also provided, which has a far lower resolution than the imager. A magnification level is selected, which results in macroblocks being defined for the sensor. A display data value is generated for each macroblock, and the set of display data values is used to drive a data display. The area of magnification is flexibly selected on the imager. As the magnification level is increased, the number of imager pixels in each macroblock decrease, enabling the display to present increasingly higher resolution images. Accordingly, an aesthetically pleasing magnification function is provided for a low-power, battery operated mobile environment.Type: GrantFiled: May 14, 2010Date of Patent: March 5, 2013Assignee: AVAAK, Inc.Inventors: Bar-Giora Goldberg, Gioia Messinger, Christopher McGill

Patent number: 8223744Abstract: A network sensor system is provided that is capable of extremely low-power operation. The network sensor system implements a communication protocol that allows the sensors to operate at most times in a sleep mode, where only a low-power time is active. In this way, each sensor's receiver, transmitter, and support circuitry are operated only when strictly necessary. The network has a defined network time frame, and each device maintains and adjusts its own clock and relationship with the network time. In this way, each sensor is aware about when it may be sent a message, and opens a short listen window only when such a message is expected. If no message is received, or if the message is addressed to another sensor, the sensor goes back to sleep. The sensor's transmitter is only activated in the case where the message 1) is received during the listen period, 2) is addressed to the sensor, and 3) requires a transmission action. Otherwise, the transmitter remains deactivated.Type: GrantFiled: May 15, 2010Date of Patent: July 17, 2012Assignee: Avaak, Inc.Inventors: Bar-Giora Goldberg, Gioia Messinger, Andy Cheng-Hsin Aoe

Patent number: 8145139Abstract: An oscillator is provided that is arranged to function as a simplified receiver. The oscillator has a resonator portion and a non-linear portion, which cooperate to generate an oscillating signal. The resonator portion is positioned to receive a modulated signal. In one configuration, the oscillator operates at a frequency offset from the frequency of the carrier for the modulated signal. In this simple arrangement, the oscillator functions as an active mixer, and generates a product output signal. The output signal is extracted from a high impedance point of the oscillator's non-linear device. The output signal is a demodulated or mixed signal, and may be further processed to detect a data signal.Type: GrantFiled: October 25, 2005Date of Patent: March 27, 2012Assignee: AVAAK, Inc.Inventor: Bar-Giora Goldberg

Patent number: 8144027Abstract: A system and method is provided for automatically reading meters, such as utility meters. A camera unit is attached to or otherwise associated with an existing meter. From time to time, either automatically, or upon wireless command, the camera unit takes an image of the meter's readings, and communicates wirelessly the image or image data, to a local area receiver. The images can be transmitted immediately, or stored for later transmission, depending on the network protocol. The camera unit is battery powered, and operates communication protocols that enable extended operational life. These protocols allow for the camera's radio and processor to be turned on only when necessary, and then for only brief periods of time. At most times, the camera is in a power-conserving sleep mode. Multiple camera units may be arranged to communicate meter image data to the local area receiver, either using asynchronous or synchronous processes.Type: GrantFiled: July 12, 2006Date of Patent: March 27, 2012Assignee: AVAAK, Inc.Inventors: Bar-Giora Goldberg, Gioia Messinger

Patent number: 8050640Abstract: An improved antenna diversity system is provided. The antenna diversity system has at least two spaced-apart antennas, with each antenna providing a respective antenna signal. The signal(s) may be processed and scaled according to its respective power level. The phase difference is determined between the signals, and the phase difference reduced by using phase rotation. The signals, which are now substantially in-phase, are summed to generate a combined antenna signal.Type: GrantFiled: October 15, 2004Date of Patent: November 1, 2011Assignee: Avaak, Inc.Inventor: Bar-Giora Goldberg

Patent number: 7327196Abstract: A fast switching phase lock loop (PLL) device is provided. The PLL has a voltage controlled oscillator that generates a signal at a frequency according to a received voltage. A memory holds a set of adjustment values, with each adjustment value set to cause the VCO to pre-tune to a desired frequency. When a new frequency is required from the VCO, the PLL counters are set for the new frequency values, and the adjustment value associated with the new frequency is retrieved from memory. A voltage generator uses the adjustment value to generate a new control voltage, which pre-tunes the VCO to a frequency near the desired frequency. In this way, the VCO only needs to make minor adjustments through its loop feedback filter to lock to the new frequency. After the VCO is locked, the actual control voltage is measured and used to update the adjusted value for that frequency. In this way, the set of adjustment values are continually updated to adapt to changing environmental or circuit conditions.Type: GrantFiled: December 5, 2005Date of Patent: February 5, 2008Assignee: Avaak Inc.Inventor: Bar-Giora Goldberg
