Abstract: A headband for a headphone, the headband comprising: a primary band for placement over a user's head to support the headphone on the user's head; and a secondary band mounted to the primary band, the secondary band rotatable relative to the primary band into one or more indexed positions to further support the headphone on the user's head.

Abstract: A hybrid-resolution panoramic VR generator places High-Resolution (HR) patches from a ring of HR cameras onto a 360-degree Low-Resolution (LR) image from a LR camera pointing upward from the ring into a panoramic mirror that captures the combined field of view of all the multiple HR cameras, but at a lower resolution. Ghosting artifacts caused by parallax errors between adjacent HR cameras are eliminated because object placement is determined by the 360-degree LR image. Each HR image is homographicly projected into 3 projections by grouping objects of different depths to obtain homographic matrixes. The 360-degree LR image is upscaled to HR and a query patch is searched in search windows in the three projections for up to two adjacent HR images. Best-matching patches are weighted by similarity with the query patch and blended to generate a reconstructed patch placed at the query patch location in a reconstructed HR panorama image.

Abstract: A bit-depth optimization engine reduces the hardware cost of a neural network. When training data is applied to a neural network during training routines, accuracy cost and hardware costs are generated. A hardware complexity cost generator generates costs for weights near bit-depth steps where the number of binary bits required to represent a weight decreases, such as from 2N to 2N?1, where one less binary bit is required. Gradients are generated from costs for each weight, and weights near bit-depth steps are easily selected since they have a large gradient, while weights far away from a bit-depth step have near-zero gradients. The selected weights are reduced during optimization. Over many cycles of optimization, a low-bit-depth neural network is generated that uses fewer binary bits per weight, resulting in lower hardware costs when the low-bit-depth neural network is manufactured on an Application-Specific Integrated Circuit (ASIC).

Abstract: Disclosed is a system and method for managing a queue of one or more service requests. In accordance with the system and the method, a queue of one or more service requests pertaining to one or more services delivered through a service location is created. Further, a queue registration request is received from a user device in order to register a service request associated with a user in the queue. Further, the queue registration request is processed to register the service request in the queue thereby recording a position of the service request in the queue. Further, the status of the queue is monitored in order to track change in the position of the service request of the user in the queue. Furthermore, the status of the queue is updated to the user on the user device thereby indicating the change in position of the service request to the user.

Abstract: A controller for a persistent display device has an overall table of waveform data corresponding to different transitions of pixels from all pixel states to all others for differing operating parameters. A hardware LUT module receives input values containing new and current pixel state data and indexes to identify update requests, stores in LUT table memory space mapping values that are segments of waveform data generated in run time according to the operating parameters of each update request, and places segments of waveform data corresponding to the update requests into LUT output memory space. A SIMD module transposes waveform data of the update requests from the LUT output memory space, and places the transposed waveform data in respective frame scan buffers. An interface receives the transposed waveform data for the display device to update an image displayed on the panel.
