09/317742

International Classification:

US Classification:

Abstract:

A new and useful sleep mode indicator system for laptop computers provides efficient use of battery power. In sleep mode, this indicator system turns OFF the typical blinking LED during the user-specified periods of unavailability. For example, a computer in sleep does not need to use electricity to identify its sleep mode status while its user is also asleep or is otherwise unavailable. This indicator system collects periods of unavailability and turns OFF the blinking LED during those periods. Also, sometimes the user may intend to operate the computer during a previously specified period of unavailability. This is reflected by the computer not in sleep mode at the start of the period and later enters temporarily into the sleep mode inside that specified period. Assuming that being the case, the present invention skips the period of unavailability just for that day. Further, the indicator system is not turned OFF any more for the rest of the specified period for that particular day.

US Classification:

Abstract:

Intelligence is added to a computer sleep mode indicator system. A method for an intelligent indicator system is provided to turn off the sleep mode status indicator of a computer during sleep mode when a user is known to be unavailable to monitor the indicator, for example, when the user is sleeping or having lunch. This embodiment also handles reasonable variations of user habits. Further, to account for a gradual change of user unavailability habits over time, this invention obtains and applies a user unavailability intelligence by dynamically modifying the beginning and the ending times of a specified user unavailability period based on user experience. One preferred method for dynamically modifying the beginning and ending times is by calculating the moving averages of the actual sleep mode entry and exit times that occurred within a pre-determined period from the specified beginning and ending times.

US Classification:

710111, 710117, 710121, 710243

Abstract:

A method and apparatus for controlling access to a plurality of resources based on multiple received requests is provided. The system includes a priority register configured to receive each individual request, determine a priority for the request, and transmit the request to a priority appropriate path. A first high priority arbiter receives and arbitrates among highest priority requests in a round robin manner to determine a high priority suggested grant vector. At least one lower priority arbiter receiving and arbitrating among lower priority requests in a round robin manner to determine at least one lower priority suggested grant vector. Grant circuitry passes the high priority suggested grant vector unless said grant circuitry receives a low priority indication, whereby the grant circuitry passes a lower priority grant vector.

US Classification:

710308, 710 22, 709250

Abstract:

A network interface between an internal bus and an external bus architecture having one or more external buses includes an external interface engine and an internal interface. The external interface engine (EIE) is coupled to the external bus architecture, where the external interface engine communicates over the external bus architecture in accordance with one or more bus protocols. The internal interface is coupled to the external interface engine and the internal bus, where the internal interface buffers network data between the internal bus and the external bus architecture. In one embodiment, the internal interface includes an internal interface (IIE) coupled to the internal bus, where the IIE defines a plurality of queues for the network data. An intermediate memory module is coupled to the IIE and the EIE, where the intermediate memory module aggregates the network data in accordance with the plurality of queues.

US Classification:

382268, 345559

Abstract:

A method and apparatus for hardware-base edge handling in video post-processing. In one embodiment, the method includes the identification of at least one unstored input pixel required to compute an output pixel during output pixel computation. Once identified, a pixel value is generated for the at least one unstored input pixel according to a detected edge handling mode. The generation of the pixel value for the unstored input pixel is performed, in one embodiment, if a position of the unstored input pixel is outside a pixel frame boundary. For example, in one embodiment, for output pixel computation of a scaling operation, the frame boundaries include a left (top) edge and a right (bottom) edge for which input pixels required to compute output pixels at or near the frame boundaries do not exist. Other embodiments are described and claimed.

H03K 7/08

US Classification:

332109, 363 2111

Abstract:

A pulse width modulator (PWM) includes a driver and a two-way integrator. The driver is coupled to output a first and a subsequent period of a PWM signal. Both the first and the subsequent periods include the PWM signal changing between first and second states. The two-way integrator is coupled to integrate an input current and coupled to generate a duty ratio signal in response to integrating the input current. The driver determines a duty factor of both the first and the subsequent periods by setting the PWM signal to the second state in response to the duty ratio signal. The two-way integrator includes a capacitor that integrates the input current during the first period by charging the capacitor and integrates the input current during the subsequent period by discharging the capacitor.

US Classification:

435403, 4242041, 4242091

Abstract:

The present invention provides novel serum-free cell culture medium and methods for cultivating MDCK cells. In particular, non-tumorigenic MDCK cells. The present invention also provides methods for producing influenza viruses (e. g. , particularly cold-adapted, and/or temperature sensitive, and/or attenuated influenza viruses) that eliminate the need for a cell culture medium exchange step. The novel medium and methods are useful to grow influenza viruses, in cell culture to high titer. The present invention further provides purification methods for purifying influenza viruses with high overall recovery of live virus and result in levels of host cell DNA (HCD), host cell protein (HCP) and non-specific endonuclease (e. g. , Benzonase), which are below the specifications required by regulatory agencies. The immunogenic compositions can be used to actively immunize subjects or to generate antibodies for a variety of uses, including passive immunization and diagnostic immunoassays.
