Abstract: Articles for supporting computers on users' laps and for isolating the users from heat from the computers. Embodiments may include a body, a top surface for contacting the computer, a bottom surface for contacting the user's lap, and back and front walls or surfaces. In various embodiments, the body defines a hollow area and a side opening, the back is taller than the front, the top surface is at an acute angle to the bottom surface, the bottom surface has a greater horizontal dimension from front to back than the top surface, the bottom surface has a greater horizontal dimension from left to right than the top surface; the article has a cross section that is a trapezoid (e.g., isosceles), the article comprises a foam portion (e.g., tubular) and fabric covering the foam portion, or a combination thereof. In some embodiments, each surface comprises the foam covered with fabric.

Abstract: Some embodiments include a case for an electrical device. The case includes a support assembly configured to be removably coupled to the electrical device. The case also includes a first portion coupled to at least a portion of the support assembly. The case further includes a second portion coupled to the first portion at a first hinge. The case also includes a third portion hingedly coupled to the second portion. The case further includes a fourth portion hingedly coupled to the third portion. The fourth portion includes a hand support assembly at an inner surface of the fourth portion. The hand support assembly includes a perimeter frame, an inner frame, and a channel between the perimeter frame and the inner frame. Other embodiments are provided.

Abstract: Some embodiments include an accessory for a mobile electronic device. Other embodiments of related accessories and methods are also disclosed.

Abstract: Carrying cases (e.g., for a computer mouse) comprising a pad and a fastener (e.g., a zipper) around the perimeter of the pad that may form a mouse pad when the fastener is unfastened, and may be folded along a dimension and the fastener fastened to form a storage pouch. Such carrying cases may include a rim to prevent a mouse from sliding off of the mouse pad, an attachment mechanism that may include a strap, a snap button, or both, or a combination thereof. Embodiments are neoprene having a thickness of 1 to 5 mm, have a fold dimension between 15 and 30 cm, or both. The fastener may have a pull tab located at one end of the fold when the fastener is unfastened and at an opposite end of the fold when the fastener is fastened. Pads may be round, oval, or rectangular with rounded corners.

Abstract: In one embodiment, a rechargeable battery pack can be configured to power an electronic device having a first battery. The rechargeable battery pack can comprise a second battery supplemental to the first battery, an external power input configured to couple to an external power source, a power output for powering the electronic device. The rechargeable battery pack can also comprise a first circuit comprising a first power path between the external power input and the power output, a second power path between the second battery and the power output, and a power switch set. When the external power source is decoupled from the external power input, the first power path is disabled by the power switch set, and the second power path is enabled by the power switch set. When the external power source is coupled to the external power input, the first power path is enabled by the power switch set, and the second power path is disabled by the power switch set. Other examples and embodiments are described herein.

Abstract: A power supply system capable of providing electric power to an electronic device having a first battery includes a battery pack (100) and an attachment apparatus (300). The battery pack includes a body (110) having at least a first recess (221), a second battery inside the body, and at least one of a first circuit (500) capable of dynamically changing a charge current supplied to the second battery based on a power consumption level of the electronic device, and a second circuit (600) capable of dynamically switching the electronic device between a recharging state and a non-recharging state depending on a status of the battery pack. The attachment apparatus includes a frame (310), an extension (350) protruding from the frame, and attachment features (461) suitable for working with the recess to attach the battery pack and the attachment apparatus to each other and to the electronic device.
