Abstract: The present application discloses an improved culinary bag. The bag is designed to carry the essential tools and devices a chef needs when working in a kitchen. The bag comprises an exterior shell and one or more detachable panels. In one embodiment, the panels can be attached to the center spine of the shell via clips and detached from the shell by releasing the clips. Each panel includes various structures such as pouches, bags, fasteners, pockets, etc. for holding various kitchen utensils and the like, as well as other accessories.

Abstract: Apparatus for detecting the presence of an object within an area under surveillance employs an electro-optical emitter for directing light into the area and an electro-optical receiver for sensing light reflected from the object which originates from the emitter. The emitter emits light energy of a preselected wavelength and is modulated at a preselected frequency to provide the emanating light energy with a characteristic signature. Light reflected by an object within the area under surveillance is filtered and converted to an electrical signal which varies in accordance with the magnitude of the filtered light having the preselected wavelength and modulation frequency. A selected portion of the electrical signal is amplified by a band-pass amplifier and is synchronously sampled in accordance with the modulation frequency to determine the magnitude of the filtered light which originated from the emitter.
