Abstract: A multiple-actuator hard disk drive includes a first actuator associated with a first logical unit and configured to operate on a first set of disk surfaces, a second actuator associated with a second logical unit and configured to operate on a second set of disk surfaces greater than the first set, and a controller accessing a mapping of logical memory addresses to physical memory locations. The mapping maps the first logical unit to the physical memory locations of the first set of surfaces and a parasitic portion of the second set of surfaces, and maps the second logical unit to the physical memory locations of the second set of surfaces exclusive of the parasitic portion of the second set of surfaces. Thus, data transfer commands performed on the parasitic portion are executed by one actuator while credit is given to the logical unit associated with the other actuator.

Abstract: Optimized 3-D graphene structures used to enhance thermal performance of the thermal systems such as vapor chambers are provided. The porosity of the wick/porous structure has a critical effect on the efficiency of a vapor chamber system. Graphene coating provides high thermal conductivity, and it has a high porous structure, which is favorable for vapor chamber devices.

Abstract: A method for determining a utilization-based fee for storing data includes determining a number of write operations for writing a quantity of data to a solid state drive (SSD) and determining an amount of a fee based on the number of write operations for writing the quantity of data to the SSD. A lifetime of the SSD can be determined based on, for example, the number of blocks in the SSD and the maximum number of write operations per block. A utilization factor for a particular workload can be determined by dividing the number of write operations in the workload by the lifetime. The value of the utilization factor can then be used to determine the amount of the fee. A bill based on the amount of the fee can be generated and transmitted.

Abstract: A data storage device includes a number of blocks in multiple dies and a controller configured to perform operations. A method of controlling the data storage device includes: translating logical addresses to physical addresses; activating one or more dies; writing data to one or more blocks; determining the number of write operations performed on the storage device; facilitating determination of a lifetime of the storage device based on a number of blocks, a particular number of write operations, and a maximum number of write operations per block; providing the number of write operations that have been performed to a host to facilitate determination of an amount of a fee, where providing the number of write operations facilitates tracking a percentage of the lifetime of the storage device.

Abstract: A modular panel for covering a portion of a structure and directing air impacting against the structure into a common path to harness wind energy includes a rear side that is adapted for mounting with the structure and a front side having a plurality of apertures therethrough. At least one central conduit leads from an inlet port on a first edge of the modular panel to an outlet port on a second edge of the modular panel. A plurality of branch conduits are each fixed between one of the plurality of apertures and the at least one central conduit. At least one of the modular panels affixed to the structure further preferably includes a wind turbine within the panel and along the central conduit. The wind turbine is adapted for receiving air from the central conduit and each branch conduit for spinning the wind turbine to produce electricity.

Abstract: A telescoping extension for a portable electronic device of the type having a camera and a wireless communication circuit comprises a telescoping arm that has a handle at a proximal end thereof and an attachment head at a distal end thereof. The attachment head telescopingly extends away from the handle with a telescoping mechanism. A device support has an attachment mechanism for slidably and pivotally fixing with the attachment head of the telescoping arm. The device support is adapted for fixing with the portable electronic device. A remote control is selectively and detachably fixed with the telescoping arm is adapted for wireless communication with the wireless communication circuit of the portable electronic device. The remote control includes a switch for communicating a command to the portable electronic device, such as a command to take a photograph, or to start or stop a video recording.
