摘要： An earpiece of an ANR device incorporates one or more of feedforward-based ANR; feedback-based ANR; passive noise reduction (PNR) of environmental noise sounds in the environment external to the casing of the earpiece in higher audible frequencies; a controlled leak acoustically coupling the front cavity to the environment external to the casing of the ANR device where the coupling may be through another cavity that is closable to the environment external to the casing with a leaky cover; a combination of an acoustically resistive port and a mass port coupling a rear cavity to the environment external to the casing where the coupling may be through another cavity that is closable to the environment external to the casing with a leaky cover; a feedforward microphone given acoustic access to the environment external to the casing through an aperture that is overlain with a leaky cover or that is enclosed within a cavity that is acoustically coupled to the environment external to the casing with a leak.

摘要： A person support apparatus comprises a lower frame, a support, and an upper frame. The support is coupled to the lower frame. The upper frame has a head section and a foot section and defines a longitudinal axis passing through the head section and the foot section and a lateral axis substantially perpendicular to the longitudinal axis. The upper frame includes a tilt mechanism pivotably coupling the upper frame to the support. The tilt mechanism includes a base and a rocker nested within the base. The base and the rocker are pivotable with respect to one another about a pivot axis that passes through the base and the rocker and is substantially parallel the longitudinal axis. The upper frame is pivotable about the pivot axis with respect to the lower frame.
