Abstract: Some examples may relate to an object-recognition system. The object-recognition system may generate an object identifier when an object having detectable elements in a predetermined spatial pattern is in proximity to a capacitive sensor. The object-recognition system may include a capacitive sensor and a reader to capture channel-capacitance measurements at least partially responsive to the capacitive sensor in proximity of the detectable elements. The object-recognition system may include a recognizer to generate an object identifier at least partially responsive the captured channel-capacitance measurements.

Abstract: A handle for a medical device includes a proximal segment defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein. A medial segment is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism limiting advancement of an endoscope attached to the distal body portion.

Abstract: A helmet air conditioning unit configured for operation with a helmet having air flow spaces within an interior space thereof, the helmet air conditioning unit including an electrical ventilating fan with a housing portion having one or more exhaust ports positionable in fluid communication with the air flow spaces within the interior space of the helmet; a battery power supply connected to energize the fan; a solar power supply coupled to recharge the power battery supply; and a fan controller coupled for actuating the fan for generating a pressurized air flow at the one or more exhaust ports of the housing portion of the fan, whereby the pressurized air flow is directed through the one or more exhaust ports of the housing portion of the fan when the fan is actuated.

Abstract: A device for gathering tissue samples includes a needle defining a distal tissue penetrating tip. The needle includes an increased diameter proximal portion extending proximally from the distal tip. An outer diameter of the distal tip is smaller than an outer diameter of the proximal portion. The needle defines a lumen extending therethrough from a distal opening in the distal tip thereof to a proximal opening at a proximal end thereof. The lumen includes a distal portion having a first inner diameter and a proximal portion having a second diameter greater than the first diameter. The device also includes a stylet slidably received within the lumen.
