摘要:
A method for controlling an inverter coupled to an electric motor for a vehicle includes generating a discontinuous PWM signal for the inverter when a torque of the electric motor and a speed of the electric motor are substantially zero, and when at least one predetermined vehicle condition is met.

A system comprises a basic-input-output-system (“BIOS”), a disk drive, and a security system configured to prevent unauthenticated access to the disk drive. For each of at least two users out of a plurality of users, the BIOS authenticates the user based on the user's token. The BIOS also accesses secured data based on the authentication, and provides the secured data to the security system without input from the user.

Exemplary embodiments of the present invention disclosed herein relate to a method of providing a system management command. The method comprises receiving from an authorized requestor information identifying the electronic device and a request to issue a system management command to the electronic device. The method additionally comprises providing, in response to the request, a system management command, information identifying a source of the command as a trusted source and the information identifying the electronic device. Also disclosed are an electronic device and a computer system according to the invention.
摘要:
A control system for an engine having a catalytic converter includes an energy calculation module that calculates a calculated mass air flow (MAF) of intake air of the engine based on a requested torque and a requested spark timing that correspond to a desired thermal energy of exhaust of the engine, and that determines an expected thermal energy of the exhaust based on the calculated MAF, and an energy residual module that determines a thermal energy residual of the exhaust based on the expected thermal energy and an estimated thermal energy of the exhaust, wherein the estimated thermal energy is based on a measured MAF of the intake air. The control system includes an energy evaluation module that determines a diagnostic result that indicates whether the catalytic converter is operating within a target temperature range based on the thermal energy residual. Related control methods are also provided.

A portable device comprise non-volatile storage. The non-volatile storage comprises a basic input/output system (BIOS) setting. The BIOS setting is applied from the portable device onto a system to which the portable device can be coupled.
摘要:
The present technique provides a system and method for automatically switching a computer system between multiple display profiles in response to a system event, such as a hardware event. The present technique detects the system event, identifies the hardware configuration of the computer system, and automatically reconfigures the computer system to accommodate the hardware configuration in real-time. The system event may be a physical rotation of a display between landscape and portrait orientations or between viewing and writing orientations. The system event also may be a physical docking or undocking of a first computing device with a second device in a variety of mounting positions. Any suitable sensor, switch, or hardware/software detection mechanism may be used for the foregoing event detection.
摘要:
A system comprises a first operating environment and a second operating environment. The first and second operating environments exchange information in encrypted form using a shared encryption key (K3). The first and second operating environments cooperate to change said encryption key K3 using another shared encryption key (K4). The encryption key K4 is changed upon the encryption key K3 being changed.

A handoff method of wireless LAN comprises the steps of: 1) immediately starting by a mobile terminal to count time from a time point of entering the wireless LAN or building the new association, that is, when building association with a certain access point; 2) always tracking a signal-to-noise ratio (SNR) of the old access point by the mobile terminal, and once the mobile terminal starts getting weak, starting to search for a near access point and making a preparation for handoff, and issuing a probe request signal to a new access point, and always responding to a probe response message by the new access point after receiving the probe request signal; and 3) judging by the mobile terminal whether or not to associate the new access point according to a signal strength and an association time of each of the access points, and if a judging result is yes, issuing the reassociation request signal to the new access point. Accordingly, the new access point issues a reassociation response message to build the new association.
摘要:
A break event in a computer system that can operate in one of a plurality of modes, such as a high performance mode and a low power mode is initiated only be logic that that detects when the transition between modes is complete. In the high performance mode, the CPU clock is faster than in the low power mode. The CPU voltage may also be higher in the high performance mode than in the low speed mode. The low power mode may be desirable for a portable computer operating from battery power in order to conserve the battery's charge. The computer system preferably transitions its CPU to a “sleep” state during the mode switch and precludes devices not associated with the mode transition from “waking” the CPU and disturbing the completion of the mode switch. Accordingly, only logic that detects the end of the mode switch can break the CPU out of its sleep state.
摘要:
A system for detecting object movement including a sensory network having at least one sensory device using modulated radar for detecting an object in proximity to the sensory network. The sensory network including wireless transmission means and a base station having computer processing means located remote from the sensory network and including wireless transmission means to communicate with the sensory network. The base station having computer readable program code means for causing the computer processing means to analyze data received from the sensory network to determine motion characteristics of the object in proximity to the sensory network.
