Abstract: A compact, autonomous motion detecting and alerting system alerts to the movement of objects of interest. Mounted on an environmentally sealed PC board are a transceiver such as a CW radar front-end, connectors, signal processors and a communications device. The system provides early warning of movement of an ice sheet or rubble field via the communication device that may be a cellular telephone. This system is mounted proximate the target surface under observation, oriented at pre-specified offset angles both laterally and in elevation. The target is illuminated and energy reflected therefrom is mixed with a portion of the transmitted signal to produce a difference frequency signal that is processed to establish existence of motion within a pre-specified velocity range. Upon verification of motion, notification is sent to a responsible authority. An autonomous or semi-autonomous power source and integral power management function may be incorporated on the same PC board.

Abstract: A probe for monitoring groundwater flow seepage velocity and direction has an electrical heater and a plurality of temperature sensors located equidistant from the heater. The probe with the heater and temperature sensors is lowered into a monitoring well and positioned so as to be immersed in the groundwater. Energy is sent to the heater, and the temperature response at the temperature sensors is measured and recorded. From the measured response to temperature, the groundwater flow velocity and direction are computed and recorded. The temperature sensors may be resistance temperature detectors, thermocouples, or any other state-of-the-art temperature sensing device.

Abstract: A device for cleaning golf-club heads comprises a receptacle for containing cleaning solution open at its upper end for receiving a golf-club head to be cleaned, and at least one brush mounted within the receptacle for engagement with the club head. An extension of a base portion projects outwardly of the device a sufficient distance to receive at least a portion of a user's foot thereon to stabilize the cleaning device when supported in an upright position on a horizontal surface. A handle may be formed on the base portion extension for conveniently lifting and transporting or for storing and draining the cleaning device. A cap may be provided for closing the upper end of the receptacle to prevent loss of cleaning liquid during transportation and handling of the cleaning device.

Abstract: A hunting blind is constructed of a set of reflectively mirrored wall panels with a camouflaged top cover, to form a rectangular structure which reflects the surrounding environment to conceal the structure of the blind. The wall panels are each preferably formed of a rigid sheet of reinforced closed cell foam material, with a sheet of mirrored clear plastic material bonded to one surface of the foam sheet. The mirrored surface of the plastic sheet is preferably secured directly to the foam sheet, thereby sandwiching the mirrored surface between the overlying clear plastic material and the foam panel to protect the mirrored surface from damage. The wall panels are rigidly but removably connected together with corner channel members to form a rigid, inflexible structure. A top closure or roof may be formed of a flexible camouflage sheet, or alternatively of rigid foam sheet having a camouflage pattern thereon.

Abstract: A catheter for retrograde perfusion of the heart through the coronary sinus, which has an infusion lumen for introducing perfusion liquid into the heart, a self inflating balloon, and a channeled flow tip at a distal end of the catheter for perfusing a cardioplegia solution into the coronary sinus.

Abstract: There is disclosed an apparatus comprising a hub that includes an annular container disposed about a central aperture for receiving an exterior portion of an indwelling tube therethrough to engage a bottom portion of the container in sealing contact with the implantation site. An extensible impervious membrane is folded within the container and is in sealing contact therewith, the membrane being arranged to form an open sleeve for receiving the tube and being coextensible therewith during withdrawal of the tube. A tie is provided to seal the sleeve about the exterior wall of tube, leaving the free end of the tube accessible to the operator. The indwelling tube can then be withdrawn through the central aperture into the coextending closed sleeve. A plastic film that adheres to the bottom portion of the container is provided for closing the central aperture to enclose the removed tube in the sleeve.
