A robotic surgical system for performing minimally invasive medical procedures includes a robot manipulator for robotically assisted handling of a laparoscopic instrument having a manipulator arm, a manipulator wrist supported by the arm and an effector unit supported by the wrist, wherein the manipulator arm provides three degrees-of-freedom by means of a first joint, a second joint and a third joint, each having an associated actuator, for robotically positioning the wrist, the wrist providing two degrees-of-freedom by means of a fourth joint and a fifth revolute joint having an associated actuator, for robotically setting the yaw angle and the pitch angle of the effector unit respectively; the effector unit includes a laparoscopic instrument actuator and provides one degree-of-freedom by means of a revolute sixth joint having an associated actuator for robotically setting the roll angle of the LIA which includes a seat, with an associated coupling mechanism for mounting an instrument stem adaptor to the effector unit, and an actuation mechanism cooperating with the instrument stem adaptor for actuating a laparoscopic instrument connected to the adaptor. The effector unit is configured such that the rotation axis of the revolute sixth joint coincides with the longitudinal axis of a laparoscopic instrument mounted to the effector unit and the effector unit includes a sensor assembly having a 6 degree-of-freedom (DOF) force / torque sensor and a 6 DOF accelerometer. The sensor assembly connects the LIA to the sixth revolute joint.

A digital-imaging based code symbol reading system which automatically detects hand-induced vibration when the user attempts to read one or more 1D and / or 2D code symbols on an object, and controls system operation in order to reduce motion blur in digital images captured by the hand-supportable system, whether operated in a snap-shot or video image capture mode. An accelerometer sensor is used to automatically detect hand / system acceleration in a vector space during system operation. In a first embodiment, digital image capture is initiated when the user manually depresses a trigger switch, and decode processed only when the measured acceleration of the hand-supportable housing is below predetermined acceleration threshold levels. In another embodiment, digital image capture is initiated when an object is automatically detected in the field of view of the system, and decode processed only when the measured acceleration of the hand-supportable housing is below predetermined acceleration threshold levels.

Methods and apparatuses for operating a portable device based on an accelerometer are described. According to one embodiment of the invention, an accelerometer attached to a portable device detects a movement of the portable device. In response, a machine executable code is executed within the portable device to perform one or more predetermined user configurable operations. Other methods and apparatuses are also described.

A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.
