Abstract: A net for fishing or other purposes. The net includes a hoop frame connected to a pole by a yoke. The yoke defines sockets in which respective arms of the hoop frame and a distal end of the pole are received. Plugs in the arms of the hoop frame desirably prevent water from passing the plugs into the hoop frame. A plug in the distal end of the pole desirably prevents water from passing the plug into the pole. The yoke and plugs provide a robust connection of the hoop frame to the pole and help retain air in the hoop frame and pole for buoyancy of the net.

Abstract: A system for monitoring at least one projectile during flight. The system includes a radar apparatus, a trigger, and a processor. The radar apparatus transmits a radar signal that includes a base radar frequency signal with a frequency shift. The radar signal has a signal profile in a direction of a chosen target and reflects off the projectile(s) traveling through the signal profile toward the target. The radar apparatus receives at least one reflected signal from the projectile(s). The trigger is operably coupled to the radar apparatus to automatically initiate operation of the radar apparatus. The processor collects data from the radar apparatus and calculates velocity of the projectile(s) based thereon. The present disclosure further provides a method of monitoring the projectile(s) during flight with the system. The present disclosure further provides a chronograph system with a housing, aiming device with a peep sight, and a trigger.

Abstract: An evaporator blower for air conditioning system that can be installed into a ceiling between existing joists. The system has a chassis dimensioned to fit between the pair of joists forms an air flow pathway through which air may be cooled by an evaporator housed in the chassis. A mounting flange is pivotally coupled to the chassis and has an opening through which the chassis can pivot between a first position below the mounting flange, and thus the ceiling, to a second position above the flange, so that the chassis is above the ceiling and between the pair of joists. A diffuser is attached to the mounting flange and provides supply and return air grilles that are in fluid communication with the air flow pathway of the chassis.

Abstract: A security and smart home system, components thereof, and associated methods. The system can include a host-carried monitor configured to monitor data associated with the host, such as motion data, position data, temperature data, or humidity data. The system can include one or more security devices located at a premises to monitor security data at the premises, with the one or more security devices in communication with a remote server programmed to process security event signals from the one or more security devices and transmit action instructions to the one or more security devices. Security devices can include an electrical power switch, an electrical power plug, and a camera.

Abstract: A knife, components thereof, a sheath therefor, and associated methods. The sheath may be releasably retainable on the blade by engagement of connection structure of the sheath and blade formed by inserting the blade into the sheath. The blade may include a bottle opener. The knife may include a finger recess adapted to receive a finger of a user when the knife is gripped by the user. The knife may be an ulu knife.

Abstract: Wellbore synthesis techniques are disclosed suitable for use in geothermal applications. Embodiments are provided where open hole drilled wellbores are sealed while drilling to form an impervious layer at the wellbore/formation interface. The techniques may be chemical, thermal, mechanical, biological and are fully intended to irreversibly damage the formation in terms of the permeability thereof. With the permeability negated, the wellbore may be used to create a closed loop surface to surface geothermal well operable in the absence of well casing for maximizing thermal transfer to a circulating working fluid. Formulations for the working and drilling fluids are disclosed.
