Oak Technology was an American supplier of semiconductor chips for sound cards, graphics cards and optical storage devices such as CD-ROM, CD-RW and DVD. It achieved success with optical storage chips and its stock price increased substantially around the time of the tech bubble in 2000. After falling on hard times, in 2003 it was acquired by Zoran Corporation. Oak Technology helped develop the ATAPI standard and provided the oakcdrom.sys CD-ROM driver that was ubiquitous on DOS-based systems in the mid-1990s. Wikipedia.

A protective case for an electronic device is provided. The protective case includes an interface for connecting to a rechargeable battery, a group of display elements, a device interface for electrically interfacing with the electronic device, and an external interface. The protective case also includes electrical circuitry configured to receive electrical power from an external power source through the external interface, exchange communications with the electronic device through the device interface, determine a charge rate for the rechargeable battery of the electronic device based on information received in the communications, and supply a portion of the received electrical power to the electronic device through the device interface if a condition is satisfied.

A protective enclosure for an electronic device is provided. The protective enclosure includes a hard shell that includes a front shell formed to a rigid shape of a front portion of the electronic device and a back shell formed to a rigid shape of a rear portion of the electronic device. The protective enclosure also includes a stretchable cushion layer over the hard shell that has a sufficient elasticity to conform to the hard shell and provide cushioning to the protective enclosure. The protective enclosure also includes a battery and electrical circuitry configured to receive electronic communications from the electronic device and distribute electrical current received from an external power source among the battery and the electronic device based on the received electronic communications.

A transponder for facilitating financial transaction communications is provided. The transponder includes a detector, a processing module, and a magnetic field source. The detector detects a first time varying magnetic field generated by a mobile electronic device. The first time varying magnetic field is encoded with financial account information. The processing module decodes the detected time varying magnetic field to recover the financial account information. The magnetic field source generates a second time varying magnetic field for detection by a magnetic read head of a point-of-sale terminal. The second time varying magnetic field is modulated with the recovered financial account information according to a sequence that corresponds to a standardized format for encoding a magnetic strip of a credit card readable by the magnetic read head of the point-of-sale terminal.

A case for an electronic device is provided. The case includes a battery, an interface to receive electrical power from an external power source, a payment device reader, a product information input device, and a computer processor configured to execute computer-readable instructions. The computer processor executes the instructions to conduct communications with the electronic device, limit an amount of current of the received electrical power consumed by the case, allocate the amount of current among the battery and the electronic device based on the communications, read product information from a product using the product information input device, and read a payment device using the payment device reader, where the payment device is used to pay for the product.
