Abstract: Disclosed is a method for execution by a computing device. The method involves establishing a communication channel for communicating with a client device using link-layer encryption, and attempting to authenticate the client device using authentication-layer encryption on top of the link-layer encryption. The method also involves receiving a command from the client device over the communication channel, and if the client device has been authenticated, executing the command. Notably, the link-layer encryption offers some degree of security because network traffic over the communication channel is encrypted, but does not offer adequate protection from all cyber attacks. However, the authentication-layer encryption adds an additional layer of security on top of the link-layer encryption, which can help to avoid or mitigate cyber attacks.

Abstract: A lithium battery module including a housing, a cover, at least one lithium battery cell and a fire retardant material is provided. The cover covers the housing. The housing and the cover form an accommodating space. The lithium battery cell is disposed in the accommodating space. The fire retardant material is filled in the accommodating space.

Abstract: A computer simulation enhanced exercise device is provided which engages the user by directly relating the users exercise motion in real time to a visual simulation or interactive game. The exercise device may comprise any variety of machines including, stationary bikes, rowing machines, treadmills, stepper, elliptical gliders or under desk exercise. These exercise devices are configured with sensors to measure physical movements as the user exercises and are coupled to computer hardware with modeling and virtualization software to create the system. These sensor measurements are then sent to a computer for use in the physics based modeling and real-time visual simulation. The computer simulation enhanced exercise device is further provided with features including manual and automatic adjustment of resistance levels, visualization of accurate caloric burn rates and correlation to everyday food items, and network connectivity providing for multiplayer network simulations and directed advertising.

Abstract: A landscape blanket to be used as ground cover in which particles such as crushed stone, marble chips and the like are arranged in a substantially single layer and are held together to form a blanket by sheets of transparent plastic material which conform to the shape of the particles and are bonded thereto without the use of adhesive. The plastic sheets are bonded to the particles by forcing them into contact with the particles while the plastic sheets are in a softened condition.
