Abstract: A system and method that allows use of a product to review its users and generates a report summarizing how closely the product has been used according to its intended use. The product includes on-board and associated I-o-T sensors to differentiate between different users of the same product and provide data correlating usage how the product is used by each user. The system and method provide recommendations regarding how a typical behavior of each user can change during its use to optimize a product's its function, lifespan, efficiency. The report additionally serves to evaluate how effective each user is at rating the product by creating a feedback evaluation report and reliability score for each user, giving weight to basically all product reviews that the user may have submitted on other products. All customer reviews submitted online by a given user can be linked, for example by username, IP address, etc.

Abstract: A scoring rule for forming a folding score on a sheet material includes a pair of score members with a scoring surface portions with individually asymmetrical flat outer surfaces extending at an angle. The score members press against a first side of the sheet material to cause a pair of laterally spaced fold score lines to be formed on the first side of the sheet material by the scoring surface portions. As the scoring rule engages the sheet material, a second, opposite side of the sheet material is compressed such that rubber-type material of an anvil of the rotary press bulges towards and forces the sheet material into an area between the pair of score members causing a self-contained single longitudinally inwardly extending groove to be formed on the second, opposite side of the sheet material along a line parallel to and positioned between the laterally spaced score lines.

Abstract: A striking wrench comprising a socket with a working side designed to cooperate with a fastener and an impact side disposed on an opposite end of the working side, a handle comprising an attachment end designed to cooperate with the socket via an interference fit to form a rigid connection, and an anvil disposed at an end of the handle opposite the attachment end. The striking wrench may also include a secondary retention element designed to further secure the rigid connection, which can be a retaining ring, a pin and tunnel, or a threaded fastener.

Abstract: Systems and methods to facilitate sleep are described. In on example, a cognitive alarm clock system for children learns sleep patterns and activities towards recommending sleep schedules and teaching independence. The system may detect the cognitive state of a child based on voice or cry pattern recognition, a time of day or night, scheduled activities, and social context, among other factors. The system may initiate actions to facilitate sleep in response to the cognitive factors. For example, the system may adjust lighting or push back a wakeup time. In another example, the system may use the cognitive analysis to teach children good sleeping habits by making recommendations to facilitate a good night's rest and encourage independence.
