摘要:
A method of establishing a trustworthiness level of a participant in a communication connection between a first communication partner and a second communication partner is proposed whereby the communication behavior is adapted to the established trustworthiness level. The participant is equipped with a trustworthiness certificate and a therefrom separated securely stored participant private key. The first communication partner receives the trustworthiness certificate from the participant wherefrom the trustworthiness level is derived and established. The first communication partner tests whether the trustworthiness certificate belongs to the participant by using the participant private key. In case the trustworthiness certificate is confirmed by the test to belong to the participant, the first communication partner communicates the established trustworthiness level to the second communication partner. Then, at least one parameter of the communication behavior is chosen in dependence of the established trustworthiness level.

Electronic devices and methods of processing and preparing processing application data are disclosed. Application data are operated on a first electronic device (2a) and a copy of said application data is operated on at least another electronic device (2b). A method call for modifying application data on the first device (2a) is translated into a more general description. The description is passed to the other device (2b). The application data on the first device (2a) is processed according to the method call. On the second device (2b), the received description of the method call is translated into a locally executable method call which is processed on the copy of application data.

Methods, system and apparatus are provided for advertising service offerings in a communication system. An example embodiment comprises at least one device. A first device broadcasts a message of a first type, chooses a value for a time limit and listens for a message sent by a second device. If no message has been received before time limit, elapse, it again broadcasts a message of a first type. Otherwise, the message received from said second device is analyzed and if said message includes valid information about said first device chooses a value for the time limit. However, if said message received does not include valid service description about said first device, a message of a second type is broadcast. This reduces useless broadcast of a complete service list. Broadcast may be initiated more often and, service discovery for new devices coming into proximity takes less time.

During normal operation of a hard disk drive, control logic controls a plurality of switching elements to provide electrical power to a spindle motor and head motor of the disk drive from a voltage source coupled to first and second voltage supply nodes (e.g., Vcc and ground), the spindle motor has a set of motor windings to which the electric power is applied to rotate the spindle motor, and the control logic is configured to enter a regenerative braking state during normal operation where the switching elements are controlled to isolate the spindle motor from the first voltage supply node and cause regenerative braking of the spindle motor so that kinetic energy due to rotation of the spindle motor is converted to electrical power that is supplied to the head motor by virtue of inductance of one or more motor windings in the set.

A system is provided for transmitting generally static media. The system (10) comprising an electronic device (12) and a digital audio transmitter (14). The electronic device (12) has a CPU (16), a storage medium (18), a display (20), a user interface (22), and a digital audio broadcast receiver (26). The digital audio transmitter (14) has a specialized broadcast server (30). The digital audio broadcast receiver (26) receives and decodes the digital audio signal transmitted by the digital audio transmitter (14).
摘要:
A process for extracting a fat from a feedstock (e.g., chocolate liquor), includes mixing the feedstock with a liquefied gas solvent (e.g., butane), filtering, washing the retentate with additional solvent, refiltering, drying, granulating, aerating the granulate, and separating the fat from the solvent in the original filtrate. The mixing, filtering, washing, refiltering, drying, and granulating are conducted under an atmosphere consisting essentially of the solvent vapor. An improved solvent extraction process includes repeatedly loading and unloading an extractor with solvent and feedstock to extract fat from the feedstock, wherein throughout loading, extracting, unloading and repeating: (a) a pressure in the extractor is continuously maintained above atmospheric pressure; (b) the extractor is continuously maintained under an oxygen-free atmosphere; and/or (c) the extractor is continuously maintained under an atmosphere consisting essentially of a vapor of the solvent.

A device for restraining an energy store is provided that includes one or more cells disposed between a first side of the energy store and a second side of the energy store vertically opposite to the first side. The device has at least one first mounting device designed for transferring a first clamping force acting in the direction of the second side to the first side of the energy store, and at least one second mounting device designed for transferring a second clamping force acting in the direction of the first side to the second side o the energy store, and at least one elastic clamping device designed for providing the first and second clamping forces and further designed for adapting a distance between the at least one first mounting device and the at least one second mounting device to a permissible distance between the first and the second side.
摘要:
The invention relates to a device for pressing a cooler against a battery, said cooler having at least one cooling surface for absorbing or dissipating thermal energy, and the battery having at least one contact surface for the cooling surface of the cooler to rest on. The device comprises a pressure part having at least one spring-elastic pressure element for transmitting a contact pressure onto a section of the surface of the cooler facing away from the battery. The device further comprises at least one suspension unit for suspending the pressure part on the battery, said suspension unit being designed such as to generate a suspension force which is counter to the contact force when the cooler is arranged on the battery and the suspension unit is suspended on the battery.
