Abstract: Disclosed is a remote control unit having a button to selectively disable and enable the physical buttons of the remote control. The remote control unit, which may be able to remotely control an electronic device, may include: a plurality of physical buttons able to receive manual input from a user; and an activator/deactivator physical button able to toggle the remote control unit between a first operational mode and a second operational mode, wherein in the first operational mode the physical buttons are enabled and pressing of the physical buttons affects the operation of the electronic device, and wherein in the second operational mode the physical buttons are disabled and pressing of the physical buttons does not affect the operation of the electronic device.

Abstract: Disclosed is a laptop computer having a physical keyboard, as well as a physical button or mechanical switch to selectively disable and enable only the physical keyboard of the laptop computer. The physical button or mechanical switch allows the user to toggle the laptop computer between two or more operational modes: a first operational mode, in which the screen of the laptop is enabled and the physical keyboard of the laptop is enabled; and a second operational mode, in which the screen of the laptop is enabled but the physical keyboard of the laptop is disabled.

Abstract: Device, system, and method of accessing electronic mail. For example, a computerized method includes: receiving an identifier of an email account, and a password; if the password matches a first reference password previously stored in association with said email account, then authorizing a substantially full access to said email account; if the password matches a second reference password previously stored in association with said email account, then authorizing a restricted access to said email account.

Abstract: Digital wristwatch, digital watch, and digital clock. For example, a digital wristwatch comprises: a clocking module able to track: (a) current real time, and (b) rounded time; and a display unit able to display at least the rounded time. Additionally or alternatively, the digital wristwatch comprises: a clocking module able to determine current real time; a rounding unit able to determine that the real current time is at least two seconds prior to a rounded horological hour, and able to calculate rounded-up horological information; and a display unit able to display the rounded-up horological hour.

Abstract: A CD player, including a CD drive, which receives a CD and reads compressed digital audio data recorded thereon, and an integrated circuit chip, which decompresses the compressed data and produces a non-compressed audio output. Preferably, the data are compressed by MPEG compression, most preferably by MPEG Layer-3 compression, so that the data are compressed approximately 12-fold, and the CD contains over 800 minutes of high-quality stereo sound recording.
