Abstract:
An ice-gripping sandal for securement to other primary footwear. The sandal comprises a sole, a toe strapping assembly and a heel strapping assembly. The sole has plural groups of cleats projecting therefrom. Some of the cleats extend at an acute angle to the longitudinal axis of the sole and include portions having ice-gripping screws. Grooves are provided between the cleats in the forefoot and toe portions of the sole. The width and depth of those grooves increase from the medial side of the sole to the lateral side of the sole to facilitate the release of material which may tend to adhere therein when the wearer walks. The toe strapping assembly includes plural flexible straps which produce an adjustable size toe box for receipt of the toe of the primary footwear. The straps of both of the strapping assemblies include VELCRO.RTM. fastening strips.
Abstract:
A circuit within a bus bridge operating in a first clock domain and a second clock domain, wherein the circuit allows data, address or any other information to be reliably transferred between the first and second clock domains regardless whether or not an internal bus clock of the second clock domain is operating in a synchronous or asynchronous fashion, while the circuit still minimizes clock skew between the internal bus clocks of both clock domains as well as any corresponding external bus clocks.
Abstract:
A connector device for releasable securement to a post of scaffolding on which a worker wearing a safety restraint member, e.g., safety belt and associated lanyard, will be disposed. The post terminates at a free upper end. The connector device basically comprises a hollow cup-shaped member formed of any suitable flexible material, e.g., a fabric of nylon or polyester, having a top portion and a downwardly extending peripheral skirt portion. The hollow interior is arranged to receive the top free end of the scaffold post therein. A reinforcing patch is disposed at the top of the hollow interior to abut the top free end of the scaffold post when it is located within the hollow interior of the connecting device. A ring, e.g., of metal, is pivotally secured to the outside of the downwardly depending skirt and is arranged to have the safety device, e.g., the lanyard, releasably secured thereto when the cup-shaped connector device is mounted on the scaffold post.
Abstract:
An ice-gripping sandal for securement to the sole of a boot or other primary footwear. The sandal comprises a sole and plural attachment straps for mounting the sandal on the boot. The sandal's sole has a bottom surface having plural ice-gripping teeth. The attachment straps are secured to the sole and comprise a short front strap and a long front strap and a pair of short rear straps. The long front strap is arranged to be extended through a loop in the short front strap and about the upper of the boot through loops in the rear straps so that its free end is connected to a buckle mounted on the short front strap at the toe of the boot, thereby forming "figure 8" strap pattern. A pair of cooperating VELCRO.RTM. fastening strips are secured onto the long strap to hold the long strap in the buckle.
Abstract:
A rope grab for protecting a worker at an elevated position from a fall. The rope grab is disposed on a vertically extending safety line and is connected to the worker by a lanyard. The rope grab includes housing having a pivotable actuator mounted thereon. The actuator includes an serrated extension for engaging the safety line. A rupturable capsule containing an indicating liquid is located in the housing. The actuator is connected to the lanyard to secure the worker to the rope grab and is pivotable upon a downward pull thereon to move the serrated extension from a first position to a second position. When the serrated extension is in the first position it engages the safety line slightly to permit the rope grab to be slid therealong. When it is in the second position it tightly engages the safety line to preclude the device from being slid along said safety line, and causes the automatic rupturing of the chamber, whereupon the indicator liquid flows onto a portion of the rope grab and a portion of the safety line. The actuator is also arranged to be moved to a third intermediate position wherein the rope grab is precluded from sliding along the safety line but the capsule is not ruptured.
Abstract:
A lanyard for connection to safety device, e.g., a belt or harness, worn by a worker and for connection to an anchor point. The lanyard is arranged to be used in a method to prevent the worker from falling. The lanyard comprising a flexible member, e.g., nylon or polyester webbing, having first, second, and third, elongated sections, each of the sections having a first end and a second end. The second ends of all of the sections are connected, e.g., sewn, to one another. Each of the first ends of the lanyard includes a respective connector, e.g., a clasp, mounted thereon. In accordance with the method of use the connector of the first section is releasably secured to the safety device, while the connectors of the second and third sections are releasably secured to the anchor point. A shock absorber may be included in the first section of the lanyard.
Abstract:
A harness to be worn by a person located at an elevated position for releasable securement to a holding or lowering device to protect the person from falling. The harness is formed of interconnected webs of flexible, e.g., nylon, material. The harness includes a pair of extendable, flexible, rapelling straps for connection to the holding or lowering device. Each rapelling strap includes a passageway through which a waist belt extends to releasably secure it to the harness. The waist belt includes a positionable tool case thereon. A positioning pad may be releasably secured to the waist belt.
Abstract:
A plurality of test cells in a cuvette is optically measured while the cuvette is manually moved through a sensing light beam. The cuvette is exposed in an open channel exposed to ambient light and is manually moved through the sensing light beam at an arbitrary rate. Abrupt changes in the optical density sensed by the beam are used to trigger the storage of the light beam intensity as an accepted measurement. The abrupt change is determined by comparing the currently read optical density of the cell against a predetermined moving average of previously read optical densities. A modulated sensing beam is received by a photodetector and converted from an analog to a digital signal by a fast A-to-D converter. The output of the A-to-D converter is coupled to a central processing unit which also includes as its input a bar code reader reading from a optically coded strip such instructions which are necessary to describe the number of cells, the test to be determined and other processing or reporting information. Abrupt changes in optical density caused by the passage of the edge of a cuvette cell triggers the generation of an accepted measurement from which an enzyme immunoassay test is performed.
Abstract:
A shoe having a slip resistant or gripping surface on the sole thereof. Preferably, the shoe is an outer shoe, such as a rubber or boot. The gripping surface is applied to the sole in separated, discrete bands within channels in the sole and comprises a mixture of a grit, such as silicon carbide, and an adhesive. The gripping surface is used to prevent or curtail slipping by the wearer on smooth surfaces, such as ice or snow.
Abstract:
An apparatus and method for providing therapeutic bubbling massage of a person's body. The apparatus may be adapted to float on, for example, a pond, lake or pool. The apparatus may be formed of an inflatable bladder having an interior volume that is pressurized with air. The weight of a user disposed on the upper surfaces of the inflatable bladder may force a portion of the bladder below the surface of the fluid in which the apparatus is floating, such that bubbles are formed when the pressurized gas is allowed to escape the bladder through openings impacting the body of the user. The gas may be heated or may be infused with an aroma.
