Abstract: A cooking apparatus includes a cooking chamber and user interface, which includes a controller, display, and memory for storing recipes. The display is coupled to the controller and displays recipes. A method includes selectively displaying recipes and selecting a manual or recipe mode. In the manual mode, a heat setting and cooking time is selected. The selected cooking time is decremented in predetermined increments and the heating element is energized in accordance with the selected heat setting, after which the heating element is energized according to a keep warm setting for a predetermined time, following which it is de-energized. In the recipe mode, a main menu is displayed, from which the user selects a recipe category. A sub menu is displayed, from which the user selects a recipe identifier associated with the selected recipe category. A list of ingredients for the selected recipe identifier is then displayed.

Abstract: A speech or phrase emitting celebration device, in the nature of a piñata, includes a longitudinal axial channel within which is placed a complementally sized integrated circuit (“IC”) including a library of pre-programmed voice chips having phrases selected by random. The circuit is responsive to impacts or shocks upon a fanciful housing of the device sufficient to actuate a shock sensor switch thereof. A speaker, in electrical communication with the circuit board of the integrated circuit, is in mechanical communication with a speaker at an end of the channel so that the emitted phrase may be heard by those in the vicinity of the device. A hollow cylindrical sensor may be disposed within the interior channel to provide appropriate input to the shock sensor switch, or a more sensitive discrete element sensor may be used.

Abstract: Compromise of a predetermined secure data processing routine by a procedure known as a "clock attack" is prevented by a method that inhibits synchronization with externally generated instructions by preventing determination of the time of execution predetermined data processing routine in relation to occurrence of an externally observable event that precedes the execution of the predetermined routine. The method includes the step of (a) randomly varying the duration between the occurrence of the externally observable event and the execution of the predetermined routine. Step (a) includes the steps of (b) executing one or more interim data processing routines between the occurrence of the externally observable event and the execution of the predetermined routine; and (c) randomly varying the duration of said interim routines.

Abstract: A descrambler for descrambling scrambled information signals through use of a predetermined decryption key. The processing means are adapted for processing data in accordance with a number of different data processing routines to descramble said scrambled information signals, including a routine for descrambling said scrambled information signals that utilizes said predetermined decryption key, and a routine for generating said predetermined decryption key.
