摘要： A sigma delta digital-to-analog (D/A) converter system (10) includes a summing device (35) at an input of a D/A converter (30), and a low frequency low amplitude wave signal (31) injected at an input of the summing device that remains unfiltered and is used to suppress spurious tone artifacts. The D/A converter system can further include an amplitude control and a frequency control for selectively adjusting the frequency and the amplitude of the low frequency low amplitude wave signal being injected. Note, the low frequency low amplitude repeating wave signal generator can take the form of a digital signal processor (DSP) (37) having the appropriate software to generate such signals.

摘要： Disclosed is a method (200) for charging energy storage devices. The method (200) can include a battery charging method in a power supply client connected by a data bus to a power supply host. The method (200) includes the steps of: detecting (210) a state of the power supply host; determining (220) a limit of current from the host to the client; allocating (230) a portion of the limit to a battery charging current; and charging (240) a battery of the client at the battery charging current such that the current from the host is greater than a recommended limit and less than or equal to the determined amount. Thus a client device can confidently charge at a rate which causes the port current to exceed a recommended limit, such as a USB port limit of 500 mA, when allowed by conditions of the host device. Advantageously, the method can help to expedite the charging time of a client battery, notwithstanding the number of other clients connected to the same host device for charging, thus minimizing the wait time of a user.
摘要翻译：公开了一种用于对能量存储装置进行充电的方法（200）。方法（200）可以包括在通过数据总线连接到电源主机的电源客户端中的电池充电方法。方法（200）包括以下步骤：检测（210）电源主机的状态; 确定（220）从主机到客户端的电流限制; 将极限的一部分（230）分配（230）到电池充电电流; 并以所述电池充电电流对所述客户端的电池进行充电（240），使得来自所述主机的电流大于推荐限度且小于或等于所确定的量。因此，当主机设备的条件允许时，客户端设备可以以使端口电流超过推荐限制（例如500mA的USB端口限制）的速率自信地充电。有利地，该方法可以帮助加快客户端电池的充电时间，尽管连接到相同主机设备的其他客户端的数量用于计费，从而最小化用户的等待时间。

摘要： Methods and apparatus for serving content to a wireless device (106) are disclosed. In an embodiment, a gateway (114), or any other suitable device or system, determines that at least one message (e.g., a text or text-like message) containing a first pointer (e.g., a unicast URL) to the content (e.g., a web page) is to be transmitted via an emergency alert system (e.g., CMAS). In response thereto, the gateway (114) obtains the content using the first pointer and generates a second different pointer (e.g., a multicast/broadcast URL) to the content. The gateway (114) provides at least a portion of the at least one message and the second pointer for transmission via the emergency alert system (118). The gateway (114) also provides the content for transmission via a wireless multicast/broadcast channel (120) based on the second pointer.

摘要： A method for locating a wireless communications device WCD (102). The method includes the step of receiving at the WCD (102) a wireless transmission comprising a first auto-location trigger signal. The WCD (102), responsive to the first auto-location trigger signal, operates in an auto-location mode. The auto-location mode includes the automatic collection and communication of predetermined first data, such as audio, video, and GPS location data. After the automatic collection and communication step of the first data is complete, the WCD (102) enters into a standby mode. The standby mode continues until a state detection device (206) of the WCD (102) detects a change in the state of the WCD (102). These changes in state are exclusive of the wireless transmission comprising the first auto-location trigger signal. The change(s) in state produce a second auto-location trigger signal, which causes the automatic collection and communication of a second data that is the same or similar to the first data.

摘要： A method is described that is for handing over a multi-mode mobile device from a first network technology to a second network technology. The method includes initiating by the multi-mode mobile device a first packet session in a first wireless network and detecting by a multi-mode mobile device a second wireless network supporting a different access network technology. The method also includes determining a Quality of Service requirement and completing pre-registration session establishment procedures for a second session in the second wireless network when the first session includes at least one of a QoS sensitive service and real time service by the first wireless network and mobile device and after completion of the pre-registration session establishment procedures the multi-mode mobile device receives service from the first wireless network and remains dormant on the second wireless network.

摘要： A mobile communication device 100 has a digital subsystem (110) and a radio frequency subsystem (108), and is powered by a battery (102) which is charged via a charge control circuit (106) using an external power supply (104) connected to the mobile communication device in a single path configuration. The mobile communication device permits limited operation of the mobile communication device by a user while the battery voltage is sufficient to power the digital subsystem but not yet sufficient to power the radio frequency subsystem. The delay in operation is minimized, however, because once charging commences, the battery voltage rises sufficiently fast that, typically, by the time the digital subsystem is initialized, enabled, and powered up, the battery voltage will be sufficient to enable the radio frequency subsystem.

摘要： A frequency synthesizer circuit, having first and second modes of operation, comprises a voltage-controlled oscillator (VCO) (64), a low-pass filter (74), a phase-locked loop (PLL) (67), an analog-to-digital converter (50), a digital-to-analog converter (56), a controller (48), and a VCO input switch. During the first mode, the VCO input switch couples the control input of the VCO to a control signal produced by the PLL, and the analog-to-digital converter measures the control signal and provides it to the controller which stores the control voltage measured by the analog-to-digital converter. During the second mode, the VCO input switch couples the control input of the VCO to the digital-to-analog converter which applies the stored control to the control input of the VCO.
