Patent number: 8995230Abstract: Methods and apparatus for using Fourier techniques to detect and isolate the fundamental frequency sweep of echolocation calls produced by bats, or of other narrow-band whistles as produced by other kinds of animals such as birds and whales. According to one example, a Fourier transform is applied on blocks of input samples to produce output frames, and a narrowband frequency modulated signal is detected and traced through the output frames. A filter is applied in each frame to attenuate frequencies above or below the narrowband signal, and an inverse Fourier transform is applied to produce an output signal. The resulting signal may then be analyzed with zero crossing techniques to measure the precise instantaneous frequency sweep.Type: GrantFiled: July 26, 2012Date of Patent: March 31, 2015Assignee: Wildlife Acoustics, Inc.Inventor: Ian Agranat

Patent number: 7782195Abstract: A method and apparatus for powering a device, such as a data recorder or other device, according to an adjustable schedule. One example of the apparatus includes a programmable timer having an alarm output, a power regulator having an enable input coupled to the alarm output, a controller coupled to the power regulator and to the programmable timer, the controller being configured to receive operating power from the power regulator, and a powered device coupled to the power regulator and configured to receive power from the power regulator. The regulator has an operating state in which the operating power is provided to the powered device and an idle state in which the operating power is not provided to the powered device. The regulator is configured to be activated into the operating state by activation of the alarm output and deactivated into the idle state by deactivation of the alarm output, under the control of the controller.Type: GrantFiled: March 19, 2008Date of Patent: August 24, 2010Assignee: Wildlife Acoustics, Inc.Inventor: Ian Agranat

Publication number: 20070237342Abstract: A method for listening to and comparing high-frequency sounds such as those produced by birds and insects by people suffering from high-frequency hearing loss, common among the aging population. Live sound is received by a microphone to produce an electrical signal. The signal is then digitized and transformed such that high frequency sounds are shifted to lower frequencies making them easier to hear. Recordings of known sources are also transformed for comparison.Type: ApplicationFiled: March 30, 2006Publication date: October 11, 2007Applicant: Wildlife Acoustics, Inc.Inventor: Ian Agranat

Publication number: 20060064759Abstract: A method of access control in which an authority may limit the content a client may download to a trusted device comprises: the authority making content, and a content descriptor containing information about the content, available to a client; the authority providing an access key to a client; the client presenting the access key and a requested content descriptor to a trusted device for download; and the trusted device accepting or rejecting the requested download as determined by the access key and content descriptor presented. Numerous variations are possible. Apparatus for limiting distribution of content obtained together with an access key in which a shared secret is encoded from a computer executing a server process comprises: a trusted device including a verifier that verifies the encoded shared secret and a content acceptor that only accepts content when the shared secret is verified.Type: ApplicationFiled: September 22, 2004Publication date: March 23, 2006Applicant: Wildlife Acoustics, Inc.Inventor: Ian Agranat
