Abstract: A method for the treatment of alopecia and in particular the problem of male-pattern baldness. By application of controlled ultrasound exposures to specific regions in the skin tissue, a physiological response will develop which causes cells in the hair follicle to increase in number, and/or new follicles to form or multiply in response to controlled damage to existing cells, leading to new hair follicles and/or increased shaft thickness in existing hair follicles resulting in more robust hair growth.

Abstract: Noninvasive pain treatment of skeletal cancer metastases in cancer patients utilizing planar or focused ultrasound. The ultrasound energy preferably targets at the Periosteum or immediate soft-bone-tissue interface, where local sensory pain receptors are directly affected by the growing tumor, to generate heat to destroy local sensory pain receptors so as to interrupt or block the pain feedback pathway to the central nervous system.

Abstract: An ultrasound probe assembly adapted for bio-imaging. The assembly comprises a catheter, an electrical assembly, including a set of linear conductors, at least partially housed within said catheter. An ultrasound transceiving unit is electrically connected to said electrical assembly and can be placed in both an undeployed state in which the transceiving unit is oriented coincidentally to said catheter and a deployed state in which it is directed to provide imaging signals over a volume of interest.

Abstract: Ultrasonic diagnostic scanheads are described which include a lighting mechanism located at the transducer end of the scanhead. The scanhead includes an integral light which is illuminated when the scanhead is connected to an imaging system. The light is color-coded in a manner which clearly identifies a particular characteristic of the scanhead such as frequency of operation. In the preferred embodiment the integral light is located in a position on the scanhead which also informs the user of the orientation of the image plane in relation to the scanhead. In accordance with a further aspect of the present invention, the light of a selected scanhead is modulated by the imaging system when the clinician selects the scanhead for use.

Abstract: An ultrasonic transesophageal scanhead is provided which enables a physician to easily and quickly change the orientation of the image plane during a scanning procedure. Means are provided on either the scanhead or the ultrasound system for selecting the imaging plane. As the imaging plane selector is actuated, an indication of the orientation of the selected plane appears concurrently on the monitor of the system along with a display of ultrasonic information of the selected plane. In a preferred embodiment the indication of the selected plane is displayed both graphically and numerically. A recording of the displayed information will thus capture both the ultrasonic information as well as the image plane orientation. A physician reviewing the recording will thereby know the exact orientation of the image being viewed, leading to a better informed and more precise diagnosis of medical conditions of the body.

Abstract: An ultrasonic transesophageal scanhead is provided which enables a physician to easily and quickly change the orientation of the image plane during a scanning procedure without disrupting control of the scanhead. Means are provided on the external control unit of the scanhead for unambiguously selecting the orientation of the plane which is imaged by the transducers at the end of the probe of the scanhead. In one embodiment of the present invention, a rocker switch is provided on the underside of the control unit, and a lighted indicator is provided on top of the control unit. When the physician desires to change the image plane, the rocker switch is rolled forward to select the transducer elements of the probe which are configured for scanning in the desired image plane. As the rocker switch is moved, the lighted indicator on the top of the control unit provides a visual display pattern aligned either longitudinally or transversely with respect to the axis of the probe.

Abstract: A keyboard system for an electronic pocket calculator or the like comprises a substrate board having a generally flat surface with a network of circuit paths thereon. The board is provided with switch contacts at a plurality of switching stations and terminals at a margin of the board for electrical interconnection to other electronic components (e.g., to the solid state logic components or the like on the motherboard of the calculator). Conductor paths and the network of circuit paths interconnect the contacts and the terminals. A dielectric layer is disposed on the substrate leaving the portions of the network of circuit paths exposed.

Abstract: A keyboard system for an electronic pocket calculator, remote TV tuner or the like comprises a substrate board having a generally flat surface with a network of circuit paths thereon. The board is provided with switch contacts at a plurality of switching stations. The switch contacts comprise at least one inner and outer contact for each switch station with the top surface of the outer contact spaced from the substrate a greater distance than the top surface of the inner contact. A switch actuating electrically conductive disc is placed over each switch station and is resiliently deformable into a position in which the disc bridges the outer and inner contacts to thereby complete a circuit therebetwen.
