Abstract:
A method for indicating storage capacity is applied in a storage device. The storage device includes a main storage unit, a capacity indicator, a driver, and a secondary storage unit. The second storage unit stores a preset storage capacity value and a drive table recording relationship between storage capacity difference ranges and rotation angles of the driver. The method includes: periodically obtaining a storage capacity value from a computer connected to the storage device; computing a difference between the obtained storage capacity value and the preset storage capacity value; determining the storage capacity difference range the difference falls within and the rotation angle the determined storage capacity difference range corresponds to in the drive table; and controlling the driver to rotate the determined rotation angle to drive the capacity indicator to indicate the obtained storage capacity value. A related storage device is also provided.
Abstract:
An optical sensing device includes a shell, at least one light emitting member, a rotator type shading member and at least one optical sensing member. The shell is formed with a black-body condition space having a light emitting chamber, a shading chamber and at least one optical sensing chamber. The light emitting member projects a light beam. The rotator type shading member is rotatably restrained within the shading chamber, and has a geometric center and a weight center offset from the geometric center. When the optical sensing device is lifted in a lifting azimuth or lowered in a lowering azimuth, the rotator type shading member is rotated by the geometric center to make the weight center located in the lowering azimuth with respect to the geometric center. The optical sensing member is arranged in the optical sensing chamber, and senses the light beam to accordingly send out a sensing signal.
Abstract:
A method for inter-network communication between a first and second user. The method includes receiving a first request for a location associated with the second user from a first switching system for a first network in response to a second request. The method processes information associated with the first request and determines a network identifier for a second network related to the location associated with the second user, and sends the first switching system a location message, including the network identifier for the second network. The method includes receiving a third request for routing information associated with the second user from a second switching system for the second network. The method determines a location directory in the second network for the second user and receives the roaming information for the second user from the location directory. The method then sends the roaming information to the second switching system.
Abstract:
This invention relates to a mobile electronic device and a power management method of a battery module thereof. The mobile electronic device includes a battery module, a charging/discharging module, and a control module. The charging/discharging module is coupled with the battery module. The control module is coupled with the battery module and the charging/discharging module. When the power supply is coupled with the mobile electronic device and the system time is not within a maintenance period, the control module controls the charging/discharging module to maintain capacity of the battery module within a first capacity range. When the power supply is coupled with the mobile electronic device and the system time is within the maintenance period, the control module controls the charging/discharging module to maintain the capacity of the battery module within a second capacity range.

For example, the process comprises contacting methanol with at least one oxidant in the presence of at least one catalyst wherein the at least one catalyst comprises at least one Group VIB metal component, such as in an amount of from about 0.5 to about 50 wt % (in terms of metal oxide) and at least one Group VIII metal component, such as in an amount of from about 0.2 to about 20 wt % (in terms of metal oxide), and at least one molecular sieve having acidic catalytic activity, such as in an amount of from about 40 to about 95 wt %, based on the total weight of the at least one catalyst for a time sufficient to obtain polyoxymethylene dimethyl ethers.
Abstract:
A PWM comprises a voltage transformation module, a voltage-sensing module and a timer. The voltage transformation module is configured to transform an input voltage into an output voltage. The voltage-sensing module is coupled to the voltage transformation module and configured to detect a voltage of a first terminal, wherein the voltage of the first terminal is proportional to the output voltage. The timer is configured to measure the time duration for which the voltage of the first terminal is lower than a reference voltage, wherein the timer initiates a short circuit signal when the time duration is greater than a predetermined value.
Abstract:
Described is a technology that provides highly accurate speech-recognized text transcripts of conversations, particularly telephone or meeting conversations. Speech is received for recognition when it is at a high quality and separate for each user, that is, independent of any transmission. Moreover, because the speech is received separately, a personalized recognition model adapted to each user's voice and vocabulary may be used. The separately recognized text is then merged into a transcript of the communication. The transcript may be labeled with the identity of each user that spoke the corresponding speech. The output of the transcript may be dynamic as the conversation takes place, or may occur later, such as contingent upon each user agreeing to release his or her text. The transcript may be incorporated into the text or data of another program, such as to insert it as a thread in a larger email conversation or the like.
Abstract:
A system and method for protecting data of network users are provided. A user end device is connected to a routing device. Then, the routing device directs data packets of the user end device into a data protection device connected to the routing device in series, according to profiles corresponding to the user end device. Security services are performed on the received data packets by the data protection device, thereby providing effective data security protection services to network users and overcoming the drawbacks of high costs and high maintenance required for self-configuration of such mechanisms in prior techniques.
