A tray and an electronic device using the same are provided. The tray used to carry an expansion card includes a base, a tray body, a sliding plate, and a limiting spring. The tray body is slidably disposed on the base and has a base portion and two side walls disposed on two sides of the base portion. The sliding plate is slidably disposed on the base portion and is able to be moved away from or close to one of the side walls relative to the tray body selectively. The limiting spring is disposed on the base portion and is used to limit the sliding plate.

Tray and electronic device using the same

A handle device is configured for a chassis body. The chassis body includes a main part and a cover plate. The handle device includes a base part and a handle part. The base part is disposed on the cover plate. The handle part includes an operative part, a coupling part and a shaft part. The coupling part is connected to the operative part. The shaft part is connected to the coupling part. The coupling part of the handle part is pivotally coupled to the base part. The shaft part is rotatably disposed on the main part. The handle part is movable relative to the base part so as to disengage the cover plate from the main part.

Handle device, chassis and server

A method and/or NFC (Near Field Communication) enabled mobile device is provided for executing an electronic contract on NFC enabled mobile devices. The (NFC) enabled mobile device applies an electronic signature thereof in an electronic contract provided on the NFC enabled mobile device used by a first contracting party, where the electronic signature is applied through a secure element of the NFC enabled mobile device. The NFC enabled mobile device determines that the NFC enabled mobile device is not within NFC range to an other NFC enabled mobile device used by a second contracting party to the electronic contract. In response to the NFC enabled mobile device determining that it is not within NFC range to the other NFC enabled mobile device, the NFC enabled mobile device sends, to the other NFC enabled mobile device, a multimedia messaging service (MMS) text message that includes the electronic contract.

Executing electronic contract on NFC enabled mobile devices

A method, system and/or NFC (Near field communication) enabled mobile device is provided for executing an electronic contract on NFC enabled mobile devices. A first contracting party is provided to apply an electronic signature thereof in an electronic contract provided on a first NFC enabled mobile device used by the first contracting party, the electronic signature is applied through a secure element of the first NFC enabled mobile device. The electronically signed contract is transmitted from the first NFC enabled mobile device to a second NFC enabled mobile device used by a second contracting party for providing the second contracting party to apply an electronic signature thereof in the received electronically signed contract from the first NFC enabled mobile device through a secure element in the second NFC enabled mobile device.

A power supply system for maintaining the efficiency of an AC/DC power conversion unit in relation to a load is disclosed. The load varies in response to power usage during operation of the power supply system. An AC power input and a DC power output of the power conversion unit direct DC power to attached components. A master controller disposed in the power supply system detects the load of an attached computer system through a DC meter and executes an algorithm to determine the values of circuit parameters of conversion circuits in the AC/DC power conversion unit. The master controller sends the values to a mode controller through a digital signal interface. The mode controller adjusts the operating mode of the conversion circuits and thus changes the efficiency of the AC/DC power conversion unit.

Efficiency adjustments in power supply system

A method, system and a computer program product for managing distribution of software updates in Near Field Communication (NFC) mobile devices includes retrieving information of one or more softwares in one or more NFC mobile devices by a NFC reader in communication range with the one or more NFC mobile devices, transmitting the retrieved information from the NFC reader to a distribution server which determines if the one or more softwares requires an update based on the retrieved information, in response to said determination, receiving an available updated software or update components of the one or more softwares from the distribution server to the NFC reader and transmitting thereof from the NFC reader to a secure element of the one or more NFC mobile devices whose one or more softwares require an updation.

Managing distribution of software updates in near field communication (NFC) mobile devices

A method of accessing local applications when roaming on a NFC mobile device may include creating a first partition and a second partition on a secure element (SE) of a subscriber identification module (SIM) of a near field communication (NFC) enabled device. The home TSM separates the first partition and the second partition by public key encryption. The home TSM generates cryptographic keys in response to a request by a roaming TSM for access to the second partition of the SIM. Following the exchange of security keys, the home TSM delegates to the roaming TSM access to the second partition of the SIM.
