217 results about "Head size" patented technology

An average head size for Men is size 7 3⁄8 (using U.S. size), 58 cm (using European size) or 7 1⁄8 (using UK size). The average head size for Women is 7 1⁄4 (U.S. sizing) .Of course, head sizes and shapes can also differ from country to country. Measuring tool: a soft cloth measure tape or a string.

Automated compulsory blood extraction system

InactiveUS6340354B1Cost-effectively mass producedPromote circulationIncision instrumentsWound drainsVeinHead size
A method and apparatus for the treatment of thrombosis, venous insufficiency, and the like, and in particular to an Automated Compulsory Blood Extraction System (ACBES) configured to provide an efficient and safe means for the measured extraction of blood utilizing a device providing, in effect, an artificial leech, but without the infection, control, care, and other limitations associated with the medicinal leech. The preferred embodiment of the present invention utilizes recent micro technological advances to provide a micro mechanical device which mimics and improves upon the bloodletting properties of the medicinal leech utilizing a micro mechanical valve, micropump, and micro sensor arraignment cooperating with a tertiary jaw array having teeth situated thereon. The preferred embodiment of the present invention contemplates an extraction device which may have a head size of one centimeter or less, and which may be utilized in number about the affected area of the patient to provide controlled, precision, pulsed blood extraction via vacuum induction, supplying a controlled dosage of anticoagulant, histamine anesthetic, or the like. Alternative embodiments of the present invention include an independent, single needle, stationary design configured primarily for emergency use, a multi-needle piston design, a large extraction area array design including concentric needles of adjustable depth, and a deep extraction needle design.

Public transport vehicle passenger flow statistical method and system

ActiveCN105512720AImprove statistical accuracyReduce the phenomenon that light mutations affect statistical resultsCounting objects with random distributionHead movementsHead size
The invention discloses a public transport vehicle passenger flow statistical method and system. Concretely, two cameras are respectively installed at the front and rear doors of a bus. The release lines of the front and rear doors of the bus and a fitting function of the camera height and the head size are determined before processing images acquired by the cameras. After a door opening signal is received, preprocessing, head detection, head tracking and head movement track analysis are performed on the images acquired by the cameras in turn, and finally passenger behaviors are analyzed according to head movement tracks, the number of bidirectional passenger flow of the corresponding doors is acquired and the number of bidirectional passenger flow of the whole bus is acquired through statistics of the number of bidirectional passenger flow of the front and rear doors of the bus. After a door closing signal is received, processing of the images acquired by the cameras is stopped, and the problem of influence on the statistical result caused by abrupt change of illumination generated by movement of the bus can be reduced. The method has advantages of high statistical accuracy so that reliable supporting can be provided for intelligent scheduling of the bus.

Head Mount Apparatus For Hands-Free Video Recording With An Electronic Device

A head mount device is worn by a person to retain an electronic device in a desirable position for hand-free use as a video recorder. A head strap assembly with tri-glide adjustment mechanisms extends from the sides and top of the main body mounting plate, allowing the device to fit most head sizes. The mounting plate is preferably an injection-molded part for holding the electronic device in a horizontal position with an elastic retention strap securing mechanism between the mounting plate and the electronic device. An elastic strap extends from an upending portion of the mounting plate, wraps around the electronic device, extends through a slot in the mounting plate, and fastens back upon itself via hook and loop fasteners to capture the device in landscape orientation. The design of the mounting plate and preferred length of the retention strap fit most modern smartphone designs by simply tightening the retention strap around the smartphone.
