Abstract: A manhole lock system includes a frame positioned over an access opening, a cover movable between a closed position in which the cover extends over the access opening, and an open position in which the access opening is exposed; and a lock mechanism for locking the cover in the closed position. The lock mechanism includes a lock member that is movable along a path between a unlocked position and a locked position, wherein in the locked position the lock member prevents the cover from moving to the open position, wherein in the unlocked position the lock member is retracted to enable movement of the cover to the open position.

Abstract: A system includes a server connected to a network. The server includes a data collection module, a database interaction module, and a predictive analysis module. The data collection module is configured to collect data, via the network, from one or more data sources, the data being related to food safety risk and sanitation compliance tracking of a food establishment. The database interaction module is configured to store, into a database, data collected by the data collection module and to retrieve data from the database. The predictive analysis module is configured to analyze data in the database and calculate, based on the analyzed data, a probability of the food establishment violating a health code.

Abstract: Various exemplary methods and devices for actuating surgical instruments are provided. In general, a surgical device can include one or more actuation shafts configured to facilitate actuation of the device. In an exemplary embodiment, the device can include four actuation shafts, two actuation shafts to facilitate articulation of the device, one actuation shaft to facilitate opening and closing of jaws at a distal end of the device, and one actuation shaft to facilitate moving a cutting element of the device. In an exemplary embodiment, each of the one or more actuation shafts can include a distal elongate member and a proximal elongate member having a proximal end attached to a distal end of the distal elongate member. The proximal elongate member can be rigid, and the distal elongate member can be flexible.

Abstract: An eyeglasses system comprises an eyeglasses frame having a pair of opposite temple regions an attachment interface at each temple region, and two or more sets of laces. The lace sets are interchangeably attachable and detachable from the attachment interfaces at the temple regions of the frame, such that laces of different styles may be used with the single frame. There are in some systems plural frames each having a pair of opposite temple regions with an attachment interface at each temple region, such that plural sets of laces may be freely interchanged and worn with plural sets of laces. Individual ones of the lace sets may include laces of one or more of different styles, colors, indicia, widths, or materials.

Abstract: A new eyeglasses with flexible attachment lace for securely holding eyeglasses to the face of a wearer. The inventive device includes a front frame and a flexible elongate lace. The front frame has a pair of opposite sides. Each side of the front frame has a loophole outwardly extending therefrom. The lace has a pair of opposite ends. One of the ends of the lace is looped through one of the loopholes of the front frame while the other end of the lace is looped through the other loophole of the front frame.

Abstract: A prothrombin time reagent is disclosed for use in a prothrombin time test. The reagent utilizes recombinant human tissue factor, phospholipids of a natural or synthetic origin, a buffer composition and calcium ion. Stabilizers and salts may also be utilized in the reagent. In addition, a method for creating lipid micelles containing tissue factor is also disclosed.
