Provided herein are cranial implant devices that include at least one acoustic, optical, and/or photoacoustic lens element comprising one or more electromagnetically translucent, electromagnetically transparent, sonolucent, and/or acoustically active materials. The cranial implant devices are structured for subgaleal scalp implantation within, beneath, and/or over at least one cranial opening of a subject and typically includes a substantially anatomically-compatible shape. In addition, the cranial implant devices permit transcranial therapeutic ultrasound, transcranial diagnostic ultrasound, photoacoustic imaging, electromagnetic wave diagnostic imaging, and/or electromagnetic wave therapeutic intervention of intracranial matter of the subject via the acoustic, optical, and/or photoacoustic lens element when the cranial implant device is subgalealy implanted within, beneath, and/or over the cranial opening of the subject. Other aspects are directed to various related systems and methods of obtaining diagnostic information from, and/or administering therapy to, a subject.

An electrolarynx includes a case housing tone-producing circuitry, a power switch to turn on the circuitry, a control button (i.e., a pushbutton) to actuate the power switch, and a pressure-sensitive-resistor (PSR) that is physically coupled to the pushbutton. The tone-producing circuitry is configured to respond to variations in PSR resistance that are caused by a user depressing the pushbutton. User-selected modes, that are selectable in one embodiment with a mode switch, include multiple frequency-varying modes (FVMs) in which the frequency of the electrolarynx tone is varied with different sensitivities to variations in PSR resistance, and multiple volume-varying modes (VVMs) for varying the volume of the electrolarynx tone with different sensitivities. A preferred embodiment provides a nonlinear frequency characteristic that facilitates operation at the low end of the pushbutton-controlled (i.e., PSR-controlled) frequency range, accomplishing same by applying suitable shape factors to frequencies of a linear frequency characteristic.

Provided herein are cranial implant devices that include a cranial implant housing configured for subgaleal scalp implantation within, beneath, and/or over at least one cranial opening of a subject. The cranial implant housing comprises a substantially anatomically-compatible shape and is fabricated from one or more sonolucent materials that permit transmission of mechanical waves through the sonolucent materials when the cranial implant device is subgaleally implanted. The cranial implant housing also includes a pressure sensor operably connected to the cranial implant housing, which pressure sensor is configured to sense intracranial pressure (ICR). The cranial implant housing also includes at least a first controller operably connected to the pressure sensor, which first controller is configured to selectively effect the pressure sensor to sense the ICR within a cranium of the subject to generate ICP data and to transmit the ICP data to an ICP data receiver. In addition, the cranial implant housing also includes a power source operably connected or connectable at least to the first controller. Other aspects are directed to various related systems, computer readable media, and methods.

A system and method for detecting lubrication conditions, lubrication regimes, impingement, stick-slip, and/or surface damage allows the health of a joint to be monitored. The system and method provides in situ or in vivo real-time monitoring of dynamic and static conditions of the joint. The monitoring system may use both passive and active sensing approaches that employ strategically placed piezoelectric transducers on/in the articulating components of the joint. In some embodiments, the transducers may be Lead Zirconate Titanate (PZT) transducers. Active sensing may be used to detect lubrication regimes under static and dynamic conditions. Passive sensing may be used to characterize the joint motion and abnormities, such as impingements and surface damages.

A system and method for allowing any surgeon, including those surgeons who perform a fewer number of a revision 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 revision procedure. An engine is operable in two distinctive selectable modes including a unidirectional mode providing only extractive forces and a bidirectional mode providing both extractive and insertional forces.
