Devices and methods in which auscultation signals, ultrasound signals, and ambient noise signals may be simultaneously acquired by a same handheld device are provided. Moreover, in some embodiments, electrocardiogram (EKG) may be acquired by the handheld device. One such device includes a housing having a sensor portion at a distal end of the housing, and a handle portion between a proximal end and the distal end of the housing. An ultrasound sensor is positioned at least partially within the sensor portion of the housing, and a first auscultation sensor is positioned at least partially within the sensor portion of the housing. An ambient noise sensor is positioned at least partially within the housing between the handle portion and the proximal end of the housing.

A multi-audio stethoscope head comprising a head body (1) including a sound collecting surface (11), a vibrating diaphragm, and a fastener. The sound collecting surface (11) is provided with a sound guiding hole (16), and the fastener (3) is provided with an axial through hole (33), a fastener sidewall (31) for attaching to the head body (1), and a diaphragm pressing portion (32) for tightly attaching the vibrating diaphragm (2) to the head body (1). The vibrating diaphragm (2) is disposed between the diaphragm pressing portion (32) and the head body (1). Protruding poles (6) protruding toward the vibrating diaphragm (2) is arranged on the sound collecting surface (11) at the radially inner side of the through hole (33), and when the vibrating diaphragm (2) is not subject to external pressure, the vibrating diaphragm (2) is spaced from the protruding poles (6).

A patient monitor including a physiological measurement logic engine receives physiological data from a physiological sensor. The logic engine abstracts one or more features of the physiological data and determines a category for the abstracted feature. The logic engine further encodes the category of each of the one or more features and determines an action to perform based on the encoded categories.

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.

Example methods, apparatus, and articles of manufacture for monitoring use by a user of a portable research device in accordance with at least one predetermined use criterion are disclosed. The disclosed examples include passively gathering data for assessing an identity of a user of the portable research device, processing the passively gathered data to produce assessment data indicating a possibility that the user is not a predetermined correct user of the portable research device, based on the assessment data, displaying a message to the user requesting a response from which the user's identity may be determined, and processing a response to the message to produce data indicating whether the user is the predetermined correct user.

A quick release structure of a diaphragm assembly of a stethoscope is disclosed, including a stethoscope having two collecting surfaces each being connectable with a diaphragm assembly. The collecting surface has a portion adjacent to an outer periphery thereof and formed with an annular fitting groove that has a height lower than the collecting surface. The collecting surface is formed with a trough. The annular fitting groove has an inclined internal wall. The diaphragm assembly includes an elastic piece combined with a diaphragm assembly. The elastic piece includes a raised rib, a projection portion, and an inclined inside surface. Through pressing the raised rib into the annular fitting groove, the inside surface is set in tight engagement with the internal wall, and this, in combination with the projection portion fit in the trough, forms a secure and stable fitting engagement and allowing easy release performed in an opposite way.
