A unique combination of several functions achieves a system by which consumers can validate the actual security status of a website before they decide to trust it, and therefore transact with it. In one example implementation, a security system includes a scanning engine that periodically and thoroughly scans the network and connected components of an on-line service such as a website. The results are stored and perhaps reported back to the service via alerts and the like. The website includes a “bug” which visitors can click on. The visual appearance of the “bug” can be altered (e.g. made invisible) in accordance with a determined level of security for the website. By clicking on the “bug,” the visitors can also be displayed web pages showing the security status of the website. Based on their review of such web pages, visitors can then decide whether to trust the website for further transactions.

A Three combination exercise table-chair device intended to reduce the pain and symptoms associated with low back pain & sciatica. This device is designed to be used by qualified operators in physical therapy offices, chiropractic offices, and rehabilitation clinics. By means of electric motors and gearboxes, the operator can adjust a moveable foot pad which raises the lower torso through varying degrees of incline to provide stretching, flexibility and range of motion. These functions are achieved by using three specific exercises of the Williams Exercise Protocol. The Williams Exercise Protocol is a specific set of exercises that are further described in the description of the device.

A method and apparatus for monitoring vehicles. The vehicles are monitored using a sensor unit. The sensor unit comprises a housing, a camera system, a wireless communications system, and a controller associated with the housing. The camera system has a field of view and is configured to generate images. The wireless communications system is configured to transmit wireless signals. The controller is configured to detect a number of vehicles in the images, generate information for the number of vehicles, and send the information in the wireless signals. The information for the number of vehicles is sent to a remote location.

A grass and leaf-clipping collector bag for lawn tractors designed to provide the ability to collect a significantly large volume of grass and leaves in a closed container before requiring emptying or disposal. The grass and leaf-collector bag attaches to the exhaust chute of the mower attachment on a lawn tractor. The bag is easily attached and removed from the exhaust chute using a quick release mechanism and is dragged on the ground behind the lawn tractor.
摘要:
A control system having a stored program digital computer for transmitting commands to digital servos for one or a plurality of punch presses; for changing new commands to correct for preceding servo errors and/or mechanical tolerance errors in the servos; for monitoring machine tool and servo condition and supervising punching, tool change and positioning operations; and having provision for assisting in the generation of coded record command tapes on the basis of incremental and/or absolute dimensional input, on a time sharing basis with automatic operation of the servos from a previously generated record tape.
摘要:
A bulbholder which is intended for accurately positioning a filament of a bulb, particularly a quartz halogen bulb, relative to a lamp reflector comprises a sheet metal body which receives a base of the bulb. A plurality of deformable legs in the form of loops serve to connect the body with a pair of flanges on opposite sides of the body. The flanges are fixed to a support and accurate positioning of the bulb filament is effected by moving the body relative to the flanges as permitted by deformation of the legs.In one embodiment, the flanges are apertured and are rivetted to a ceramic support. In another embodiment, the flanges have arcuate lipped edges which are brazed to an annular surface on the support.
