An imaging needle apparatus, associated system, and method of use are described. The apparatus includes various interchangeable modules, including a trocar assembly, a blunt cannula assembly, and an arthroscope assembly, such as a nano-arthroscope. For example, using the imaging needle apparatus, a doctor can treat a patient by inserting the trocar assembly into the patient's body, inserting the blunt cannula assembly into the body via the trocar assembly, removing the trocar assembly, and inserting the arthroscope assembly into the blunt cannula assembly. Further, the imaging needle apparatus, in some embodiments, includes a light engine that provides a light source for a camera cannula of the apparatus, such as a camera cannula that is part of the arthroscope assembly.

A full-bridge class-D amplifier circuit comprises first through fourth power devices. First conduction terminals of the first and third power devices are coupled to a first power supply voltage, and second conduction terminals of the second and fourth power devices are coupled to a second power supply voltage. A second conduction terminal of the first power device and a first conduction terminal of the second power device are coupled to a first amplifier output. A second conduction terminal of the third power device and a first conduction terminal of the fourth power device are coupled to a second amplifier output. Left and right driver devices respectively disposed adjacent to left and right sides of the first power device have outputs respectively coupled to left and right control terminals respectively disposed on the left and right sides of the first power device.

Bridged class-D RF amplifier circuit

A transient noise reduction filter comprises a cable including one or more twisted pairs of conductors and one or more common mode chokes (CMCs). The one or more CMCs a formed from respective pluralities of turns of the cable. Each of the CMCs may be a magnetic CMC wherein the plurality of turns of the cable are wrapped around a magnetic core, or an air-core CMC wherein the plurality of turns of the cable are not wrapped around a magnetic core but are instead disposed around a non-magnetic material (such as air)

Transient noise reduction filtering system

A control signal may be produced in response to an assertion of a switch signal by asserting the control signal, waiting an adaptive delay after the assertion of the switch signal, de-asserting the control signal in response to the expiration of the adaptive delay, and re-asserting the control signal in response to a current generated according to the control signal becoming zero. The adaptive delay may be adjusted according to a voltage generated using the current. A circuit may include an XOR gate producing the control signal from a switch signal and an output of a Set-Reset Flip-Flop (SRFF), a zero-detect circuit that resets the SRFF when a current generated using the control circuit becomes zero, and a delay circuit to set the SRFF an adaptive delay after assertion of the switch signal and to adjust the adaptive delay according to a voltage generated by the current.
