Abstract: A hairbrush may include a head portion, a handle extending from the head portion, and a cushion selectively coupleable with the head portion. The cushion is configured to be selectively loaded with one or more bristle bars, and each bristle bar may contain one or more bristles extending therefrom. The cushion may include a plurality of bristle openings arranged in rows. Each row of bristle openings can be loaded with no bristle bars, one bristle bar, or two bristle bars. When a row of openings in the cushion is loaded with two bristle bars, the two bristle bars are interlocked with one another along their respective lengths.

Abstract: A hair brush may include a body, a number of bristles extending away from the body, and a replaceable cartridge removably attached to the body. The cartridge may include a housing, a reservoir positioned at least partially within the housing, and an applicator positioned at least partially within the housing. The reservoir may be configured to store a hair care treatment therein and may include a first porous material. The applicator may be configured to apply the hair care treatment to hair of a user and may include a second porous material. The hair care treatment may be optimized for delivery via the reservoir and the applicator.

Abstract: A shield and a method for shielding are provided for preventing radio frequency energy from entering or exiting an electronic device. The shield includes a frame surrounding the electronic device. The frame has a first frame wall and a second frame wall arranged with a first gap in between that extends along the first frame wall. The first frame wall is arranged in a first plane, the second frame wall is arranged in a second plane, and the first plane intersects the second plane. The shield also includes a cover surrounding the frame. The cover has a first cover wall and a second cover wall arranged with a second gap in between that extends along the second cover wall. The arrangements of the first gap and the second gap prevent radio frequency energy from entering or escaping the electronic device.

Abstract: A rugged housing is provided for an electronic device, such as a cellular telephone. The electronic device has sides extending across a length and width of the device, a top extending across the width and a thickness of the device, and a bottom extending across the width and thickness of the device. At least the sides of the device are shaped irregularly and unsymmetrically. The housing includes a first portion and a second portion. The first portion surrounds the sides and the top of the electronic device in a continuous and seamless manner. The second portion is connected to the first portion and extends across the bottom of the electronic device. The second portion may be disconnected for inserting component parts of the device into or removing component parts of the device from the housing. These components parts include a power source, a keypad, and/or a display.
