The present subject matter relates to recognition of simultaneous key presses in a keyboard. The keyboard includes a first group of keys, which includes keys that are to be individually recognized when pressed simultaneously with at least one other key of the first group. Keys of a first sub-group of the first group are connected to key switches that are to be connected to general purpose input/output (GPIO) pins. Keys of a second sub-group of the first group are connected to key switches on at least one of mutually different columns and mutually different rows of a matrix of electrical interconnections. The second sub-group includes at least one key that is not a modifier key.

An electronic apparatus having key tops that can be illuminated without cooling performance being affected is described. The electronic apparatus includes: a chassis and a keyboard device having a set of key tops; a base plate for supporting the key tops; a membrane sheet laminated on a top surface side of the base plate; a light guide plate laminated on a bottom surface side of the base plate; and a light source module for irradiating the key tops with light via the light guide plate. The keyboard device, which is located on a top surface side of the chassis, includes an inlet port for passing air in a top-bottom direction and a set of individual light sources arranged respectively on bottom surface sides of a part of the key tops that is located to overlap the inlet port.

Temperature probe hubs are disclosed. An example temperature probe hub includes a housing, a drain, and a probe jack. The drain extends through the housing. The probe jack is located within the housing in fluid communication with the drain. The drain is configured to remove fluid from the probe jack.

A key structure includes a keycap, a connection assembly, engaging members, and a base plate. The connection assembly disposed between the base plate and the keycap is movably connected to the keycap and the engaging members, so that the keycap and the connection assembly engaged with the engaging members are positioned on the base plate. The base plate includes engaging protrusions protruding from an upper surface, so that the engaging members are bonded to the base plate through the engaging protrusions. Each engaging protrusion is located between two openings of the base plate, connects the two openings, or is disposed corresponding to the openings. Each engaging member covers one or more engaging protrusions through injection molding, and is fixed to the base plate. The engaging members are respectively disposed on the openings, fill the openings, or completely cover the engaging protrusions.
