The present invention provides a stethoscope head switchable between a digital mode and a conventional mode. The stethoscope head comprises a housing, a chestpiece, a switching mechanism, a microphone, a speaker, and a first power switch. The microphone is configured for receiving acoustic signals from the chestpiece. The speaker is configured for playing the acoustic signals received by the microphone. The first power switch is configured to be engaged by the switching mechanism. The switching mechanism is configured for switching the stethoscope head between the digital mode and the conventional mode when engaged by the first power switch.

A personal protection device includes one or two elongate members for engaging into the nostrils of the nose of a user. The elongate members each includes gridded ports for allowing air to pass through the elongate member when breathing in and for allowing air to exit via the elongate member when breathing out. Sensors are placed in the air flow pathway to detect pathogen presence, and the primary air filter is positioned in the elongate member. In yet other embodiments, a disposable version is disclosed. The eyewear can also be used as part of an extended reality system, and when game playing, particularized scents can be rendered to the nose to enhance the gaming experience. In another aspect, systems and methods protect against pathogen by sampling an environment of a travel path with a plurality of pathogen detectors along the travel path to detect a presence of one or more pathogens, wherein at least one detector includes a nano-sensor with receptacles to bind to the pathogens and wherein the nano-sensor changes resistivity, inductance or capacitance upon pathogen binding; directing air towards said pathogen detectors; contact tracing a user mobile device having a mobile identification (ID) carried by each user, wherein the mobile device comprises a memory storing mobile IDs of all devices within a predetermined radius of the user mobile device; and performing deep learning with a neural network receiving data from the pathogen detectors and to the user mobile device to detect a presence of one or more pathogens.

A system and method for allowing any surgeon, including those surgeons who perform a fewer number of a replacement procedure as compared to a more experienced surgeon who performs a greater number of procedures, to provide an improved likelihood of a favorable outcome approaching, if not exceeding, a likelihood of a favorable outcome as performed by a very experienced surgeon with the replacement procedure. Force sensing is included to aid in quantifying installation of an implant, particularly a cup into a pelvic bone.

The invention relates to a stethoscope comprising a stethoscope chestpiece comprising a body member having a bottom surface and an ejector mark disposed on the bottom surface. The stethoscope chestpiece has a weight of at least 50 g, a surface roughness (Ra) no greater than 1.6 microns in an unpolished state, and reflectivity (% R) of at least 60% in an unpolished state. The stethoscope chestpiece can be produced by injection molding, extruding, or pressing a metallic thermoplastic composition into a mould forming a green molded body, debinding a portion of binder material from green molded body forming a brown molded body without reducing the temperature by more than 80° C., and sintering the brown molded body to form the stethoscope chestpiece.

Aspects of the present disclosure relate to an ergonomic chestpiece for a stethoscope. The chestpiece includes a bottom surface which is generally planar and adapted to be placed near the patient for receiving auscultatory sounds. The chestpiece includes a raised center portion defining first and second lateral indented gripping surfaces, the raised center portion having a top surface opposite the bottom surface. The chestpiece includes a stem portion extending distally from the raised center portion. The first lateral indented gripping surface is defined by a first wall comprising a first concave surface arcuate about a first axis and the second lateral indented gripping surface is defined by a second wall comprising a second concave surface arcuate about a second axis. The first axis and the second axis form a V-shape comprising an apex oriented in a direction of the stem portion.
