摘要:
In a system with a policy server, a first device able to communicate with the policy server and a second device able to communicate with the first device and unable to communicate with the policy server, the first device is to act as a policy proxy. The policy server may communicate to the first device a policy for the second device, and the first device may communicate the policy to the second device.
摘要:
Different target transmit powers are determined for different wireless transmissions from a wireless device, the different transmissions having different security requirements. For example, the security requirements of a particular transmission may include a security ranking of a device to which one or more frames carried by the particular transmission are addressed. In another example, the security requirements of a particular transmission may include the confidentiality of data carried by the particular transmission.
摘要:
A differential calorimetric gas sensor (10) which includes a sensing element (12) having a catalytic layer (14) disposed on a multi-layered substrate (26). Catalytic layer (14) includes an active catalyst region (14a) which oxidizes total combustibles within an exhaust gas stream and a reference catalyst region (14b) which oxidizes selective combustibles within the exhaust gas stream. An electrochemical oxygen source (18) is disposed on an opposite side of multi-layer substrate (26) from sensing element (12). An oxygen sensor cell (170) may be incorporated into electrochemical oxygen source (18). The multi-layered substrate (26) includes a plurality of overlaying insulating layers in which an intermediate layer (60) and a bottom layer (64) support primary heaters (58, 62), and in which another intermediate layer (52) supports compensation heaters (50a, 50b). The primary heaters (58, 62) function to maintain sensor (10) at a substantially constant temperature, while the compensation heaters (50a, 50b) function to restore temperature deviations determined by temperature-sensitive elements (46a, 46b) located on an inner layer (48) overlaying the compensation heaters (50a, 50b) resulting from the catalytic reactions taking place at the surfaces (34a, 34b) of the catalyst regions (14a, 14b). The control circuitry (300) operates to control the primary heater (58, 62) and the compensation heaters (50a, 50b), as well as to minimize the response variations of the temperature-sensitive elements (46a, 46b).
摘要:
A calorimetric hydrocarbon gas sensor (10) includes an electrochemical oxygen pump (18), a sensing element (12), and a multi-layered substrate (26) separating the sensing element (12) from the electrochemical oxygen pump (18). The multi-layered substrate (26) includes a plurality of overlying insulating layers, in which at least one intermediate layer (60) supports a first primary heater (58), and in which another intermediate layer (52) supports a temperature compensation heaters (50a, 50b). The primary heater (58) functions to maintain the calorimetric hydrocarbon gas sensor (10) at a constant, elevated temperature, while the active compensation heater (50a) functions to maintain substantially equal temperatures as determined by the thermometers (46a, 46b) located on an intermediate layer (48) overlying the compensation heaters (50a, 50b). Control circuitry is integrated with power measurement circuitry to measure differences in the heat produced by the compensation heater (50a) and the thermometer (46a) in an active region (100), and the heat produced by the compensation heater (50b) and the thermometer (46b) in a reference region (102).
摘要:
A method for updating an electronic mail (“email”) address book comprising: determining whether an email message presented to a user on a display screen of a data processing system contains address information; and, if the email message contains address information: identifying the address information in the email message; determining whether the address information is contained in one or more contact records in the email address book; and, if the address information is not contained in one or more contact records, presenting first means to the user on the display screen for generating a command to add a new contact record to the address book for the address information.
摘要:
Rendering subject information for a protected message received and stored at an electronic communications device, wherein the message is initially received by the electronic communications device without subject information. Selected information is extracted from the protected message and stored on the electronic communications device as subject information for the protected message.
摘要:
Upon recognizing a loss of a first connection to a computing apparatus, such as a personal computer, a smart card reader may maintain an open session with a smart card and may associate an identity of the computing apparatus of the first connection with the open session. Some time later, the smart card reader may establish a second connection with a computing apparatus. The smart card reader may compare an identity of the computing apparatus of the second connection with the identity of the computing apparatus of the first connection. Responsive to determining that the identities do not match, the smart card reader may close the open session with the smart card. Responsive to determining that the identities do match, the smart card reader may maintain the open session with the smart card.
摘要:
An embodiment relates to a novel apparatus and method for changing modes of notification in an electronic device. An electronic device includes a calendar application and a variety of other applications such as the message reader application or the daily alarm application. The device is configured to use the calendar application to track whether and how the user is notified of the receipt of an electronic message. In one embodiment, the user specifically associates a profile behavior to the calendar entry when the calendar entry is first created.
摘要:
A command destined for a smart card is received. If the command is of a state-altering type that places the smart card in a known state, it is relayed to a smart card reader unless the smart card is currently in the known state. If the command is a POWER OFF command, it is relayed to the smart card reader unless (i) the smart card is currently in the known state and (ii) within a predetermined time from receiving the command, a subsequent command of the state-altering type that places the smart card in the known state is received. If the command is not a POWER OFF command and is not of the state-altering type that places the smart card in the known state, it is relayed to the smart card reader. The command is discarded if not relayed to the smart card reader.
