Abstract: A swivel device with rotation damping, adapted to rotationally couple a hoist cable to a hoist hook, the device including: a first disc fixedly mounted on a central axle and adapted to be operationally coupled to a distal end of the cable by a non-rotating coupling; a second disc rotationally mounted on the central axle and spaced apart from the first disc, the second disc adapted to be operationally coupled to the hoist hook by a non-rotating coupling; a first set of magnets mounted on the first disc; and a second set of magnets mounted on the second disc, magnetic fields of the first set of magnets interacting with magnetic fields of the second set of magnets to damp rotation of the second disc about the central axle.

Abstract: According to one aspect, the invention provides a method for detecting pest infestation within a body. The method comprises the steps of a) providing an imaging system comprising at least a radiation source, a detector, a processing station and a display monitor; b) positioning at least a section of the body between the radiation source and the detector; c) acquiring a first image of said section of said body; d) acquiring at least one second image of the section of the body; e) removing the common portion of the images by subtracting the first image from the second image, thereby resulting in a digitally subtracted image; and f) observing determining from the digitally subtracted image and determining whether at least one pest is present within the body. Pest infestation may be detected without physical contact with the tree.

Abstract: Methods and devices for intracorporeal therapeutic illumination using an implantable light source are disclosed. The present invention can be used for short, intermediate and/or long-term light therapy of all internal tissues, organs and organ surfaces, including the blood, in the treatment of inflammatory, infectious, arthritic, allergic, musculoskeletal and parasitic pathologies. The implantable light source comprises a wide range of modifiable wavelengths and other light therapy parameters and can illuminate remote intracorporeal locations via optional fiber optic connection. Direct phototherapy of the blood is effected by implantable intravascular light sources, optical fiber conduits, a unique light source-bearing intravascular tubular platform or a novel, light emitting vascular prosthesis. Power and modulation of the light therapy parameters is provided by implantable power and control modules or, in preferred embodiments, by external sources in telemetric communication with the implanted light source.

Abstract: Scalp apparatus for regulating the temperature of the scalp of a wearer. The scalp apparatus includes a helmet for coveting the hair bearing scalp of the wearer, spacing means to provide an air space between the helmet and the scalp of the wearer and relating apparatus for regulating the temperature of the helmet so as to relate the temperature of the air space such that the scalp of the wearer is maintained at a desired temperature. The relating apparatus can be in the form of thermoelectric elements and a power supply for providing electrical power to the thermoelectric elements or a potion of piping and a source of fluid for providing a flow of liquid through the potion of piping. The apparatus can further include thermostate apparatus for controlling the regulating apparatus. The scalp apparatus can be employed for cooling the scalp of a wearer to combat the problem of alopecia during chemotherapy treatment or for warming the scalp of the wearer during heat treatments.
