摘要:
Teachings herein prepare a digital image for display on a substantially transparent screen. The teachings advantageously recognize that the perceptibility of the digital image on the screen will often depend on what is visible to a user through the screen, since that will effectively serve as the background of the screen. A method of preparing a digital image thus includes dynamically calculating which part of an environmental background is visible to a user through the screen and thereby serves as an effective background of the screen. This calculation may entail obtaining an image of the environmental background and identifying which part of that image serves as the effective background (e.g., based on the angle at which the user views the screen). The method further includes composing the digital image for perceptibility as viewed against that effective background and outputting the composed image as digital data for display on the screen.
摘要:
A parallel processor (10) having a plurality of parallel computational lanes (L 0 -L 7 ). The parallel processor (10) comprises a data-vector generation unit (40). The data-vector generation unit comprises a first input port (50) for receiving a first vector of data elements from a memory unit (30) and a second input port (60) for receiving a control vector. The data-vector generation unit further comprises an output port (70) for outputting a second vector of data elements to the plurality of parallel computational lanes (L 0 -L 7 ). The second vector comprises more data elements than the first vector. The data-vector generation unit (40) is adapted to generate the data elements of the second vector based on the data elements of the first vector and the control vector. A method of operating the parallel processor (10) is also disclosed.

A WLAN router connected via a cellular network (e.g. LTE) to the Internet is disclosed; a plurality of SIMs (subscriptions), each associated with a user of the router, may be plugged into the router (or soft SIMs used); simultaneous Internet access for a plurality of users is achieved, even if the WLAN router does only have one TX/RX equipment, by the following features: the WLAN router—when receiving a portion of network traffic for a user—determines the subscription that the portion is associated with and updates a data usage quota for the subscription accordingly by an amount of data corresponding to said portion; thereafter, it is decided whether future network traffic for that subscription shall be transmitted over the same network connection or another subscription's network connection based on the updated data usage quota; thus, the router carries out load balancing between the subscriptions.
摘要:
A common narrow-band speech signal is expanded into a wide-band speech signal. The expanded speech signal gives the impression of a wide-band speech signal regardless of what type of vocoder is used. Extending the narrow-band speech signal into a lower range involves analyzing the narrow-band speech signal to generate one or more parameters, and synthersizing a lower frequency-band signal based on at least one of the one or more parameters. The synthesized lower frequency-band signal is then combined with a signal that is derived from (e.g., via up-sampling) the narrow-band speech signal. In preferred emobodiments, a pitch frequency parameter is generated, and generation of the lower frequency-band signal includes generating continuous sine tones that are frequency shifted with the pitch frequency parameter.
