    摘要: A multimeter having an elongated housing with a fixed recess for receiving a current-carrying conductor is provided. The multimeter is adapted to measure various parameters including a.c. and d.c. voltage, resistance, and a.c. current. On one end of the elongated housing of the multimeter is a C-shaped current sensor mounted around the fixed recess for measuring a.c. current in the current-carrying conductor and on the other end is a pair of test leads for measuring resistance, a.c. voltage, and d.c. voltage. The current sensor and the test leads provide input signals to an analog-to-digital converter (ADC) to obtain digital samples which are displayed as measurement results according to the selected measurement mode.

    摘要: Keyboard input functionality is provided when a removable portion of the keyboard is docked into the base unit. The removable portion may be the undocked from the base unit. A keyboard removable portion may include alphanumeric functionality and may be of a reduced size for off-desk implementation. Since the base of the keyboard may be wired, it may also charge the removable portion of the keyboard. The base may also include the wireless receiver for cooperating with a wireless keyboard or wireless mouse.

    摘要: A mouse has sufficient width to support the distal phalanges of a user's ring finger and little finger while the user's middle finger is positioned over a secondary button of the mouse. The mouse also provides at least one side button positioned so that it is not contacted by the user's thumb during “pinching” of the mouse but is easily accessible by the user's thumb. In addition, the mouse provides a wheel with a large number of ribs that increase friction between the user's finger and the wheel.
