Abstract: A patient rotation device including an armature and a patient engagement assembly. The armature is structurally configured for attachment to an outside structure. The armature has a first end and a second end spaced apart from the first end. The patient engagement assembly includes a housing and a rotational assembly. The housing is attachable proximate the second end of the armature. The rotational assembly includes an axle and a rotational member. The rotational member is rotationally coupled to one of the housing and the armature, and structurally configured to be being positionable over a surface of a bed. Methods are also disclosed.

Abstract: Chainsaws having chain tensioning biasing elements are provided. A chainsaw includes a housing comprising a geartrain; a guide bar extending from the housing; a chain moveably coupled around the geartrain and the guide bar; a motive device operatively coupled to the geartrain that selectively drives the geartrain to cause rotational movement of the chain around the guide bar; a tension adjustment assembly configured to selectively move the guide bar relative to the housing to adjust a tension in the chain; and a tension biasing element that continuously imparts an expansive force on the guide bar and/or the chain to oppose a loosening of the tension in the chain.

Abstract: An apparatus and method for obtaining a client program grammar communication from an Application Programming Interface (API) call. The API call is first obtained. When metadata is associated with the API call, the associated metadata is obtained and a best estimation of the client program grammar communication is obtained from the associated metadata and from the API call. Otherwise, a best estimation of the client program grammar communication is automatically obtained from the API call.
