Abstract: A portable storage device can include a memory and one or more connectors for connecting to other devices. During use, a user can connect a remote device such as a smartphone, tablet, or the like to the portable storage device in order to transfer data from the remote device to the memory of the portable storage device. The portable storage device can include a rechargeable power source configured to provide the necessary electrical current for establishing communication between the remote device and the memory of the portable storage device. The portable storage device can further include one or more photovoltaic devices for generating electrical energy and recharging the rechargeable power source of the portable storage device.

Abstract: Embodiments of the invention include a caching device for temporary storage of content generated using a content-generating device. The caching device and the content-generating device can be operatively coupled. The caching device can be worn on a user's body. The caching device includes a housing, a power source supported by the housing, a storage device adapted to store content, and an antenna supported by the housing. The antenna can transmit or receive content from/to the storage device to/from a content-generating device. The caching device can consume low power and can transfer content at low data rates.

Abstract: Aspects of the invention generally relate to a portable storage device having a memory and a plurality of connectors. The portable storage device can include a first connector for connecting to a first remote device, such as a smartphone or tablet. The portable storage device can receive digital data from the remote device, or can transfer digital data to the remote device. The portable storage device can include a second connector for connecting to an external device, such as a computer. Similarly, the second connector can enable the two-way transfer of digital data between the external device and the portable storage device. The portable storage device can include a third connector for connecting to a second remote device to enable the two-way transfer of digital data between the portable storage device and the second remote device. The portable storage device can facilitate data transfer between remote and external devices.

Abstract: Aspects of the invention generally relate to a portable storage device including a memory and a rechargeable power source. The portable storage device can include one or more connectors for connecting to one or more remote or external devices, such as a smartphone, table, computer, and the like. The portable storage device can receive digital data for storage in memory from one or more connectors, or can provide access to digital data in its memory to a remote or external device via the one or more connectors. The rechargeable power source can provide electrical power to a device via one or more connectors for recharging a battery of that device, or can receive electrical power from a source via the one or more connectors for recharging the rechargeable power source.

Abstract: Aspects of the invention generally relate to a portable storage device having a memory and a standard connector for connecting to a variety of other devices, such as smartphones, tablets, computers, or others. For example, the standard connector can be configured to interface with a cable having a corresponding standard connector on one end and a device-specific connector on the other such that the cable provides the connection between the portable storage device and the other device. The portable storage device can interface with one of such other devices via the standard connector to receive digital data from the other device for storage in memory, or can allow access to digital data stored in memory by the other device.

Abstract: A reading light such as is clipped onto the back of a book has two illuminating color zones; one being yellow/white and the other being blue/white. These are provided by separate LEDs. These LEDs are mounted on one or more arms which can be pivoted from a closed state to a deployed state. A manual switch allows the user to switch between the two different colors of illumination or select both at the same time. This approach enhances user comfort in reading the illuminated material. Certain materials and certain ambient light favor the use of a yellow/light illumination color while other materials and other conditions favor the use of a blue/white illumination color. This provides visual comfort for the user who can select which of the light color ranges is most comfortable and can select both if that provides greater comfort.

Abstract: An adapting device for adapting a first portable media player to emulate selected mechanical and electrical characteristics of a second portable media player includes a housing having first and second connectors. A signal converter is operatively connected to the first connector and the second connector for converting a first signal representing at least one command received over the second connector into a second signal representing the command to be transmitted over the first connector. A mechanical interface is configured to interconnect the second connector with an accessory device that accommodates a second portable media player having the second connector.

Abstract: An electronic handheld tutorial device having a display, an input element, a memory and a processor. The memory contains databases to enable a user to prepare for a test. The processor processes inputs from a user received from the input element and administers the test and provides a complete diagnostic analysis for the results of the test on the display.
