Abstract: The present invention relates to an organic matter biodigester comprising a tank that has an organic matter inlet, a first connection arranged in an upper portion of the tank and a second connection arranged in the lower portion of the tank. Furthermore, said tank also has a biogas outlet and a lower surface configured to rest on a support surface. Furthermore, the lower portion of the tank is at a shorter distance from the support surface compared to the upper portion of the tank. Said organic matter biodigester also comprises a manual pump with a pump inlet connected in the second connection, and a pump outlet connected in the first connection of the tank. The pump is configured to recirculate the organic matter inside the tank from the second connection towards the first connection; and a porous layer arranged inside the tank.

Abstract: A display device establishes a secure communications session with a mobile device and receives an image-based item associated with a unique cryptographic token. The display device determines, based on metadata parsed from the unique cryptographic token, authenticity information and chain-of-ownership information for the cryptographic token. In response to determining that user account information for the secure communications session corresponds to an item included in the chain-of-ownership information, the display device displays the image-based item, and an indicator component of the display device provides an indication of authenticity for the image-based item.

Abstract: There is provided a method that includes initiating a transmission of a first media program of one or more media programs from a provider to a primary receiver authorized to receive the first media program, the first media program having media content, and receiving media data from a secondary receiver, the media data generated by the secondary receive from the media content reproduced and provided by the primary receiver to the secondary receiver. The method also includes comparing the media data received from the secondary receiver with the media content transmitted by the provider to the primary receiver to determine a match between the media data received from the secondary receiver and the media content transmitted by the provider to the primary receiver, and authorizing reception of the one or more media programs by the secondary receiver when the comparing determines the match.

Abstract: A method, apparatus, and system for authorizing reception of one or more media programs of a content provider by a secondary receiver based upon reception of the media program by a primary receiver is disclosed. In one embodiment, the method comprises the steps of receiving location data from the secondary receiver, initiating authorized reception of a transmitted first media program having audio content of the one or more media programs by the primary receiver, receiving the audio content of the media program reproduced by the primary receiver from the secondary receiver, and authorizing reception of the one or more programs of the content provider by the secondary receiver according to the received location data and a comparison of the received audio content of the media program and the audio content of the transmitted first media program.

Abstract: An acoustic hailing device includes an outer housing and a pair of compression drivers oriented in the outer housing adjacent one another. Each of the compression drivers includes two diaphragms oriented facewise relative to one another within each compression driver. One or more waveguide housings are coupled to the outer housing, the one or more waveguide housings forming a portion of a waveguide associated with each of the compression drivers. A pair of driver covers are each coupleable to one of the compression drivers, each of the driver covers forming another portion of the waveguide associated with each of the compression drivers.
