A print head assembly and a printer using the same are disclosed. The print head assembly includes: a bracket, a print head and an elastic element. The bracket includes a first bracket body having a cavity and a lid covered on the opening of the cavity. A window is opened on the first bracket body. The print head is accommodated in the cavity of the first bracket body and hinged to the first bracket body via a first rotary shaft. The surface of a heating element of the print head is matched with the window and faces an outside paper pressing roller. The elastic element biases towards the print head so as to make the surface of the heating element of the print head have a tendency to extend outside the window. The print head assembly is capable of being detached as a whole, thus the requirements of performing single-sided printing and duplex printing in the same printer is achieved.

The present invention relates to an adaptive step size method for power control in wireless communication systems and a system for the same. The method includes the steps: obtaining the power control information whose number is previously set in previous power control cycle and that in current power control cycle; Determining the power control step size in current power control cycle according to the obtained power control information whose number is previously set in previous power control cycle and that in current power control cycle. Employing the method to determine a suitable step size in current PC cycle, we can overcome the defect that the change of the PC step size in current wireless communication system is a fixed value, thereby make the power change more smooth, and ensure that wireless communication holds better communication quality.

摘要:
A single-stage amplifier includes (1) first and second “gain” transistors coupled in a common source configuration, (2) first and second resistors providing self-biasing for the first and second transistors, respectively, (3) first and second current sources providing bias currents for the first and second transistors, respectively, and (4) a load impedance coupled between the drains of the first and second transistors. The amplifier may further include (5) third and fourth “compensation” transistors coupled in parallel with, and used to compensate parasitic capacitances of, the first and second transistors, respectively, and (6) third and fourth resistors providing self-biasing for the third and fourth transistors, respectively. Variable gain may be achieved by varying the bias currents for the gain transistors. A two-stage amplifier may be formed with two stages coupled in cascade, with each stage including most or all of the circuit elements of the single-stage amplifier.

This invention relates to a device, a method, a computer program and a computer program product for a device capable of communicating in a first mode of wireless communication and a second mode of wireless communication simultaneously, wherein it is determined for each of at least one channel of a plurality of channels whether interference occurs between the first mode and the second mode; and wherein the channels which have been determined not to cause interference are stored in a list of preferable channels. For instance, in the case where the first mode represents a cellular communications mode, during a cell selection/reselection procedure of the first mode, instead of searching in the cell information stored for the PLMN, it will first search in the list of preferable channels when the second mode is active.

摘要:
The present invention provides a wireless communication network system that maintains uplink control for the mobile terminal in peer-to-peer communication. According to one embodiment of the invention, after determining a reliable direct communication link can be set up between the mobile terminals, the network system transmits information including control commands to the mobile terminals for establishing direct communication. The information includes a burst structure type, with the burst structure containing at least one section for carrying control information intended for the network system. After the direct communication is established, the network system continuously listens to signals communicated between the mobile terminals to receive bursts. The network system demodulates received bursts that are communicated between the two mobile terminals to determine whether a received burst contains control information intended for the network system. If control information intended for the network system is included in a received burst, the network performs a corresponding function. In this way, the uplink control for the mobile terminals can be effectively maintained in peer-to-peer communication.
