An apparatus is used for testing an embedded device with identification information. The apparatus includes a storage device. A monitoring program and a testing program are installed in the storage device. The monitoring program receives the identification information from the embedded device through a serial connection formed between the apparatus and the embedded device after logging in to the embedded device through the serial connection. The testing program is copied to the embedded device to test the embedded device by the monitoring program through a network connection formed between the apparatus and the embedded device. A system and a method for testing the embedded device are also provided.

A handle has opposed ends and a central extent. A grip rotationally receives the central extent of the handle. An adjustment wheel is secured to each end of the handle. A side cover is fixedly secured to each end of the grip. A dowel disk is on the handle adjacent to one side cover with fingers and spaces. A plurality of cam bits are supported on the handle. A safety lock is within the side cover adjacent to the dowel disk. The safety lock has a first end extent and a second end extent with a radial recess and a central extent with an axial projection. A coil spring within the radial recess urges the safety lock radially outwardly.

摘要:
A secure framework for wireless sensor networks. The framework provides a system and method for providing network device authentication. The system and method comprises installing a unique device key in a network device and creating a chain of keys, wherein each subsequent key is encrypted using the previous key. The method executes an authentication process for storing and issuing keys, wherein the authentication process uses a unique device key to install a device site key in the network device and uses the device site key and the unique device key to authenticate the network device for communicating with a wireless network router, wherein the wireless network router creates a unique network-device-router key. The unique network-device-router key is used to authenticate the network device for communicating over the wireless network using an encrypted network session key and allows secure encrypted link-layer communications over the wireless network.
摘要:
A method and apparatus for providing input voltages to power amplifiers (PAs) is disclosed. For one embodiment, a multiple-mode device having a corresponding PA for each mode is provided with a voltage adjustment mechanism that adjusts the output voltage from the switcher based upon the PA that is currently in use. The voltage adjustment mechanism may be controlled by firmware or software of a digital processing system (DPS) of the host device. The voltage adjustment mechanism may include a digital potentiometer controlled by the host DPS.
摘要:
Each of a plurality of weights has a central hole and a slot extending through the central hole. A shaft has a grip handle. A rotatable spindle extends through the grip handle with a plurality of cam plates adjacent to each end of the spindle and an adjustment knob at each end of the spindle. The cam plates each have an outer diameter adapted to fit the central hole of a weight. The weights include a set of weights positioned adjacent to each end of the rotatable spindle and adjacent to the cam plates. A holder is cooperable with the shaft with protrusion blocks adapted to cooperate with the shaft to form a self-locking mechanism.
