Various embodiments concern locking release mechanisms that allow an articulated support arm to be moved between various vertical orientations. A locking release mechanism may include a handle release mechanism positioned within the handle of the articulated support arm, and a gas spring release mechanism positioned within the body of the articulated support arm. The articulated support arm can include a gas spring that remains locked until the handle release mechanism is activated, e.g. by applying pressure to a grip actuator. Other embodiments concern cable management techniques for articulated support arms. Oftentimes, an articulated support arm will include cables routed through the arm that are configured to support an attachment. For example, the cable(s) may be adapted for audio signals, video signals, power, etc. The cable(s) can be readily cleaned and/or serviced when routed through an articulated support arm composed of one or more removable pieces.

A point-of-care computer system is provided, including a display positioned in a point-of-care location. The point-of-care computer includes hardware coupled to a frame of a hospital bed.

A suspension device making it possible to suspend items of equipment (7, 7) under a support structure comprises an anchor bracket (2) designed to be anchored axially to the support structure, two distribution arms (9, 10, 9, 10) that are adjustable up and down and that are designed to carry the items of equipment (7, 7), and that are connected to the anchor bracket (2) via pivot articulations (11, 11), each of which is offset from the anchor bracket (2) via a stationary offsetting arm (8, 8; 8).

Method and system allowing more accurate detection and identification of unwanted arcing include novel processing of signal voltage representing recovered power-line current. In one implementation, arc-faults are detected based on numerical analysis where individual cycles of line voltage and current are observed and data collected during each cycle is processed to estimate likelihood of presence of arc-event within each individual cycle based on pre-defined number of arc-events occurring within pre-defined number of contiguous cycles. In another implementation, fast transient current spikes detection can be done by: computing difference values between consecutive line-current samples collected over a cycle, average of differences, and peak-to-peak value of line-current; comparing each difference value to average of difference; comparing each difference value to peak-to-peak value; and, based on calculation of composite of two comparisons, using thresholds to determine if arcing is present within processed cycle.

A medical device support system including a shaft, extension arm, and floating stop. A guide channel member is fixed to the shaft and includes an elongated cavity that defines first and second contact faces at its opposite ends. A hub of the extension arm is pivotably mounted for a range of at least 360 degrees rotation about a rotation axis of the shaft. The at least 360 degrees rotation range is based on a compound of a first rotation range and a second rotation range. The first rotation range is defined by a fixed stop of the hub configured to move between first and second contact faces of a radially outer portion of the floating stop. The second rotation range is defined by a radially inner portion of the floating stop configured to move between the first and second contact faces of the elongated cavity of the guide channel member.

A mounting plate for a medical device support system includes opposed major surfaces in a thickness direction. A group of plate mounting orifices is arranged in a hexagon pattern and extends through the opposed major surfaces and defines a perimeter of an area at the major surfaces. A primary orifice extends through the opposed major surfaces, and a group of primary spindle mounting orifices surround the primary orifice and extend through the opposed major surfaces, the primary orifice and the primary spindle mounting orifices located within the defined area. An auxiliary orifice extends through the opposed major surfaces and a group of auxiliary spindle mounting orifices surrounds the auxiliary orifice and extend through the opposed major surfaces, the group of auxiliary spindle mounting orifices defining a perimeter of an auxiliary spindle mounting area at the major surfaces, one of the plate mounting orifices located within the auxiliary spindle mounting area.

A power transfer system comprises a patient support apparatus and a power transfer device. The power transfer system provides convenience and ease of connection between a power source and the patient support apparatus to provide power to one or more electrically powered devices on the patient support apparatus or to provide energy for an energy storage device on the patient support apparatus.

A medical device support system including a shaft, an extension arm, and a free rotating ring. The shaft includes an elongated peripheral cavity that defines first and second contact faces at opposite peripheral ends. A hub of the extension arm is pivotably mounted for a range of at least 360 degrees rotation about a rotation axis of the shaft. The at least 360 degrees rotation range is based on a compound of a first rotation range and a second rotation range. The first rotation range is defined by a fixed stop of the hub configured to move between first and second contact faces of a radially outward protruding member of the free rotating ring. The second rotation range is defined by a radially inward protruding member of the free rotating ring configured to move between the first and second contact faces of the elongated peripheral cavity of the shaft.

A suspension arm assembly including at least three horizontally aligned members relatively rotatable about each other. Each adjacent pair of members are connected to each other by a joint. At least one conduit extends along the at least three horizontally aligned members, with the at least one conduit being routed horizontally along the horizontally aligned members and not being located within a periphery of the at least three horizontally aligned members.
