Techniques for providing self-voice feedback in a communications headset include processing signals carrying near-end speech in parallel digital and analog signal processing paths to produce a combined gain-adjusted near-end signal carrying the near-end speech for output to transducers of the communications device.

Self-voice feedback in communications headsets

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.

Feedforward ANR device cover

The present invention is a self-developing compact camera having a housing that encloses, in a common cavity thereof, an arrangement comprising a taking lens, shutter, a light-reflector, viewfinder, power source, actuator, a self-developing film compartment, and a spring biased exit flap. The present invention also includes a method of manufacturing said camera.

Compact photographic camera

A self developing photographic apparatus comprising: a housing including a film exit slot; exposure means operable for effecting an exposure; a film assemblage of the self-developing type including at least one exposable area and a rupturable reservoir containing processing fluid being associated with a corresponding exposable area. The apparatus also includes pressure applying means operable for rupturing the reservoir to thereby dispense and spread the fluid over the exposable area so as to initiate development of latent images as the film is withdrawn from the housing. Also included is at least one film engaging assembly coupled to the housing and located exteriorly of the film exit slot. In another embodiment, the invention includes a method of processing a film assemblage such that the film spreading fluid is applied substantially uniform.
