  • Patent number: 11939615
    Abstract: The present invention discloses a production method of enzymatic reaction using adenosine instead of ATP. The method comprises the following steps: (1) adding ATP regeneration enzyme, AK enzyme and adenosine in proportion to carry out an enzymatic reaction in an enzymatic reaction system; (2) separating the ATP regeneration enzyme and AK enzyme by either directly separating ATP regeneration enzyme and AK enzyme immobilized in a reaction tank or separating free ATP regeneration enzyme and AK enzyme by an ultrafiltration membrane in a filter; and (3) separating and purifying the filtrate of step (2) to obtain a product. The disclosed method provides: greatly reduced industrial production costs; faster reaction rate; stable enzyme recovery system that is energy efficient and environmentally friendly; and capability of reusing the byproducts or collecting them for the production of ATP.

  • Patent number: 11375244
    Abstract: An apparatus of embodiments, as described herein, includes one or more processors to track data associated with movement of a computing device accessible to a user, and evaluate the data and compare a latency with latency thresholds, where the data indicates the latency and the latency thresholds associated with a frame. The one or more processors are further to maintain a current video encoding rate, if the latency is lower than a first latency threshold and greater than a second latency threshold. The current video encoding rate is decreased if the latency is equal to or greater than the first latency threshold, where the current video encoding rate is increased if the latency is lower than the second latency threshold. The one or more processors are further to present the frame at the computing device including one or more of a wearable device and a mobile device.

  • Patent number: 11367452
    Abstract: Techniques are provided for spatial audio streaming using adaptive bitrate encoding and decoding in bandwidth limited virtual reality applications. A methodology implementing the techniques according to an embodiment includes calculating weight factors for audio channels associated with each of a plurality of microphones. The weight factors are based on the position and head angle, relative to the microphones, of a user wearing a head mounted display (HMD). The method also includes encoding and decoding the audio channels, for transmission to the HMD, at a selected bitrate, the bitrate based on the weight factor for the audio channel. The method further includes applying an adaptive gain compensation to each of the received and decoded audio channels, the gain compensation also based on the weight factor. The method further includes mixing the resulting gain compensated channels to generate a stereo audio signal to be played through speakers of the HMD.

  • Publication number: 20140286133
    Abstract: A method for determining orientation of an electronic device relative to another electronic device is described. The method includes synchronizing internal clock of a first electronic device with internal clock of a second electronic device using electromagnetic signals communicated between the first electronic device and the second electronic device, sending two or more sound waves from the second electronic device, receiving the two or more sound waves at the first electronic device, and calculating orientation of the first electronic device relative to the second electronic device based on a difference in time of arrival of the two or more sound waves at the first electronic device. The first electronic device and the second electronic device each have at least one transceiver configured to send and receive electromagnetic signals. The first electronic device has two or more acoustoelectric transducers and the second electronic device has one or more acoustoelectric transducer.

  • Publication number: 20130163453
    Abstract: An ultrasound and radio frequency technology is used to implement presence sensor capability for wireless devices such as, a laptap device. For example, the laptap device connects to a station device through a WiFi signal. In this example, the WiFi signal may include a data packet that synchronizes internal clocks of the laptap device with the station device. Further, the data packet may include transmitting time information for an ultrasound audio signal generated by the station device. The ultrasound audio signal is received by the laptap device that calculates time of flight (TOF) of the ultrasound audio signal. The TOF may be used to determine actual distance of the wireless device (e.g., laptap device) to the station device.
