Abstract: An artificial retinal prosthesis is disclosed for electrically stimulating a retina of an eye by spatiotemporal electrical stimulation to provide color visual perception. The prosthesis comprises a plurality of pixel group units, each including a main pixel unit and at least one auxiliary pixel unit. The main and auxiliary pixel units are driven according to different sequences of cycles, each cycle comprising a dark period followed by a lighted period, such that the pixel units intermittently output lighted pulses. During the lighted periods, the main pixel unit is nominally turned on for at least one lighted duration except for an off duration while the auxiliary pixel units are continuously turned on for the entire lighted period. During the dark periods, both the main pixel unit and the auxiliary pixel units are continuously turned off for the entire dark period.

Abstract: An artificial retinal prosthesis is disclosed, which comprises a plurality of pixel group units to output a spatiotemporal electrical stimulation for inducing color perception. Each of the pixel group units comprises a main pixel unit and at least one surrounding pixel unit. The main pixel unit and the surrounding pixel unit respectively outputs an electrical stimulation waveform according to a first stimulation cycle and a second stimulation cycle. Both of the first stimulation cycle and the second stimulation cycle have a first-half duration and a second-half duration. The first-half duration of the first stimulation cycle has inactive period greater than 20% and less than 80% and the rest of the first stimulation cycle is active period. The second-half duration of the first stimulation cycle is inactive period. The first-half duration of the second stimulation cycle is active period and the second-half duration of the second stimulation cycle is inactive period.

Abstract: A mattress for patient care. The mattress includes a number of compressible cells and a number of sensors corresponding to the number of compressible cells. Each compressible cell is configured to contact, when inflated, a user in a contact area of a plurality of contact areas of the user. Each sensor is configured to generate a number of measurements, wherein each measurement relates to the contact area of a corresponding compressible cell. Each sensor is further configured to send the number of measurements to a pressure control device.

Abstract: An adjustable container carrying strap structure includes a strip-shaped carrying strap and a container sleeving assembly. The strip-shaped carrying strap includes a first end, a second end, and a carrying strap body. The container sleeving assembly includes two sleeve ropes and an adjusting element, where each sleeve rope includes a first rope end, a second rope end, and a rope body, the first rope end of each sleeve rope is connected to the first end, the second rope end of each sleeve rope is connected to the second end, and the adjusting element is assembled on the two rope bodies of the two sleeve ropes, so that the adjusting element, the two rope bodies, and the first end of the strip-shaped carrying strap encircle a container sleeving hole. The adjusting element can slide relatively along the two rope bodies so as to adjust the size of the container sleeving hole.

Abstract: The subject disclosure pertains to systems and methods for providing a user interface for mobile devices. The user interface can include a search function that utilizes user input to search multiple software applications and data sources. Content can be retrieved and presented to a user without requiring the user to navigate to the underlying application or sources supplying the content. The applications or content sources can be local to the mobile device or remotely located, such as an Internet site. One or more types of data can be retrieved and presented to a user based upon the user input. Search results can be displayed and dynamically updated as additional user input is obtained.

Abstract: When a user types in one or more characters from a restricted or ambiguous character set, such as numbers from a keypad, the characters in the restricted or ambiguous set are mapped to a larger set of characters, such as the alphabet. Then, the larger mapping set is used to search through keywords representing options available on a communications device, options available through the Internet, and possibly options available through paid placements. The set of options that are returned are then sorted based on past user behavior, on the context the device was in when the search was initiated, and optionally, on weightings given to selected keywords through paid placement.

Abstract: When an input device, which may be a portable communications device, receives a keyword input from a user, an advertisement associated with the keyword, and stored on the device, is displayed. Then, a signal is transmitted to a remote site which indicates that the advertisement was displayed. In some embodiments, an advertiser pays a fee associated with the advertising being displayed, and may also pay a fee to place the advertisement on the device. A user has the option of turning off the advertisements, and/or of being paid a fee when the advertisements are displayed on his or her device. Specific advertisements may be displayed based on the physical location of the device.
