Abstract: An energy conveying structure for invasive electrosurgery that provide for combined delivery of (i) RF or microwave electromagnetic energy for tissue treatment (e.g. ablation, coagulation or cutting), and (ii) optical radiation within a common structure that may form an instrument cable of a surgical scoping device. The structure resembles a hollow coaxial transmission line with an optical channel formed within it. The optical channel can lie within a passage that is formed within the inner conductive layer or within other layers of the coaxial transmission. The structure may be used to form an electrosurgical device capable of delivering RF/microwave EM energy, optical radiation and ultrasonic signals to a treatment site along an instrument cable of a surgical scoping device.

Abstract: In some embodiments, an apparatus includes an antenna; a radio-frequency (RF) tuning network configured to receive an input signal via the antenna; an RF energy harvester operatively coupled to the RF tuning network and configured to produce a direct current (DC) output based on the received output of the RF tuning network; and a load manipulator configured to be transitioned between a first configuration and a second configuration to manipulate one or more properties associated with the RF energy harvester such that an input impedance of the RF energy harvester changes from a first input impedance to a second input impedance. The first input impedance is associated with a first distribution of RF energy associated with the input signal relative to the RF energy harvester and the second input impedance is associated with a second distribution of RF energy associated with the input signal relative to the RF energy harvester.

Abstract: The present disclosure relates to systems and apparatus that provide for integration of different respiratory therapies into a single system, or provide for integrated switching between separate systems or apparatuses delivering different therapies such as anaesthesia and high flow therapy. Aspects of the disclosure relate to various systems, devices, apparatuses, switching mechanisms and multi-lumen lumen assemblies for integrating control of these therapies and providing flexibility in how and where a user controls switching between therapies.

Abstract: A fishing wader with a body portion and a pair of booties. The body portion has a front pocket assembly made of three stacked layers of material, including an outer layer having a plurality of hexagonal-shaped holes, a water-permeable middle layer, and a water-permeable inner layer. Each bootie has a toe piece, an ankle piece, and a sole piece. The toe piece has a top layer that is a laminated composite material including a waterproof breathable membrane. The toe piece also has a middle layer that is made of a durable and resilient waterproof material with a plurality of cutouts that penetrate completely through the middle layer. The toe piece also has a bottom layer. The durometer of the sole piece is preferably higher than the durometer of the toe and ankle pieces.

Abstract: Aspects of the disclosure relate to methods, apparatus, and systems for mitigating signal attenuation at a body-worn device transmitting a radio signal. An antenna structure for the body-worn device includes an antenna array configured to radiate at least one radio signal and a conductive band capacitively coupled to the antenna array. The conductive band is configured to detachably couple to a body of a user, and mitigate attenuation of the at least one radio signal when the conductive band is coupled to the body. The conductive band mitigates the attenuation by facilitating a radio frequency (RF) signal current corresponding to the at least one radio signal to flow through the conductive band and preventing absorption of the RF signal current by the body.

Abstract: A combined light and loudspeaker driver device comprising a housing supporting a loudspeaker driver, a heat removal element, electronic components and a light source. The heat removal element includes a column extending along a central longitudinal axis to a base of the housing, to meet a heat sink formed around the central longitudinal axis to the rear of the housing. The light source provides task lighting and is a heat source. It is mounted on a front end of the column distal from the heat sink at the base of the housing, to optimize conduction of heat away from the light source. The housing is generally cup shaped and has side walls. The interior of the side walls is parallel with the central longitudinal axis of the housing over the majority of the rearward depth thereof resulting in a large void behind the loudspeaker diaphragm, leading to improved sound.
