Abstract: This invention provides a support device that allows the adjustable, yet rigid placement of a probe or other medical instrument against a region of interest/treatment on a patient. The system and method of rigid fixation, positioning, and adjustment contemplated herein is useful for a broad array of medical procedures including, but not limited to, ultrasound-guided anesthetic delivery. In an exemplary embodiment of the present invention, a flexible armature is attached to a rigid stand placed upon the floor, or attached to another stable surface such as a bed rail, wall, ceiling or piece of equipment. A joint connects the armature to an instrument holder able to accommodate and rigidly attach an ultrasound sensing probe or other medical device. The medical device then remains rigidly attached to the described invention during the procedure. Furthermore, this set position is resistant to minor patient motion or other disturbances.

Abstract: A lane marker of the present invention utilizes a housing and filler to support and protect a solar powered energy storage system. The circuitry draws power from solar cells and stores the energy in 5-20 storage capacitors. When the ambient light dims, the circuitry operates a timing device which causes one or more light emitting diodes located behind an angled clear window, to blink in a direction generally of the approaching traffic. The top of the housing protects a solar cell which is in operating position is mounted above the filler and below a clear upper window. The storage capacity may be varied by increasing or decreasing the capacitance used for energy storage. The duty cycle can be adjusted to levels consistent with sunlight and operating time. Geographic areas of high solar radiation can use the invention set safely have a higher duty cycle without depleting the stored energy, while areas of lower solar radiation can use the inventive circuit set for a lower duty cycle.
