A data storage caching architecture supports using native local memory such as host-based RAM, and if available, Solid State Disk (SSD) memory for storing pre-cache delta-compression based delta, reference, and independent data by exploiting content locality, temporal locality, and spatial locality of data accesses to primary (e.g. disk-based) storage. The architecture makes excellent use of the physical properties of the different types of memory available (fast r/w RAM, low cost fast read SSD, etc) by applying algorithms to determine what types of data to store in each type of memory. Algorithms include similarity detection, delta compression, least popularly used cache management, conservative insertion and promotion cache replacement, and the like.

Biomaterials with enhanced properties such as improved strength, flexibility, durability and reduced thickness are useful in the fabrication of biomedical devices, particularly those subjected to continuous or non-continuous loads where repeated flexibility and long-term durability are required. These enhanced properties can be attributed to elevated levels of elastin, altered collagen types, and other biochemical changes which contribute to these enhanced properties. Examples of devices which would be improved by use of such tissue include heart valves, including percutaneous heart valves, and vascular grafts, patches and the like. Such enhanced materials can be sourced from specific populations of animals, such as neonatal calves, or in range-fed adult cattle, or can be fabricated or created from cell populations exhibiting such properties. In one embodiment, glutaraldehyde-fixed neonatal pericardial tissue is used to create leaflets in a percutaneous heart valve, and may be used without chemical fixation, with or without processes to remove residual cellular membranes, and utilized as a scaffold material for tissue engineering.

The autonomous system uses a series of ultrasonic sensors to calculate the position of the robot relative to obstacles which allow for safe autonomous movement

A shift position switching device for shifting gears in association with a shift position. The device includes a shift mechanism switching between shift positions using a drive power of a motor, an encoder outputting pulse signals in sync with a rotation of the motor, and a controller rotating the motor to a target rotation position corresponding to an intended gear. The controller rotates the motor toward a dead-end on a first shift position side of the shift mechanism while observing a motor rotation speed or an acceleration of rotation of the motor based on the outputted pulse signals of the encoder. Also, the controller learns, as a reference position on the first shift position side, a first rotation position of the motor.

A two module keyboard with splash-resistant mechanism has a key module that can be separated by a user from a base module. One group of components becomes a detachable and user-serviceable key module, while the other group stays as the base module. The detachable module contains essentially the keycap portion that causes substantially more malfunctioning of present day keyboard components than the rest. The base module has a bay that receives the detachable key module, and contains the electrical circuitry membrane and PCB that has longer durability than the key portion. Drain holes at lower end of the bay will allow liquid spillage, or water/solution if used to clean the bay, to flow out of the keyboard. Depending on applications, the detachable key module can be further broken into more sub-modules. Keyboards made according to the present invention are modular in nature, and are conducive to reducing the costs for keyboard related services and exchanges, costs for curing accumulative environmental hazards and costs for fitting suitable user keys for swapping among different languages and computer applications.
