Abstract: In some embodiments, an apparatus includes a set of memory modules configured to store data and a reprogrammable circuit module operatively coupled to the set of memory modules. The reprogrammable circuit module is configured to receive, from a host device, information associated with a search request. The reprogrammable circuit module is configured to change from a first configuration to a second configuration in response to receiving the information. The reprogrammable circuit module is configured to retrieve at least a portion of the data stored at the set of memory modules associated with the second configuration. The reprogrammable circuit module is configured to generate a search result based on the portion of the data, and transmit the search result to the host device.

Abstract: In some embodiments, an apparatus includes a set of memory modules, a reprogrammable circuit module and a set of data channels. Each memory module is associated with an address translation table configured to store a set of address pairs each including a physical memory address and a logical memory address. The reprogrammable circuit module is configured to retrieve a first physical memory address associated with a first logical memory address and a second physical memory address associated with a second logical memory address. Each data channel couples the reprogrammable circuit module to at least one memory module. The reprogrammable circuit module is configured to send a first and a second query to the first and the second memory module, via a first data channel based on the first physical memory address or a second data channel based on the second physical memory address, respectively.

Abstract: Video data is compressed, at a first site, by a transform scaling data compressor (12), and carrier signals are modulated with audio and digital data by a delta modulation data modulator (14) and a delta-sigma modulation data modulator (16) respectively. Their output signals are combined by a multichannel data compressor (18) and transmitted to a second site, where the procedures are essentially reversed to effectively regenerate the data as originally formatted.

Abstract: A device for teaching music using coded indicia representing musical notes and being scannable, a scanning wand and circuits for decoding the signals from the scanning wand and producing audible tones of the proper pitch.
