Workers who are engaged in working on equipment often require specialized equipment beyond the regular screwdrivers, pliers and wrenches. Through trial and error certain tools have been found to be invaluable, most of those combining multiple functions into a single tool. More options in a single tool mean fewer tools and lighter loads but each industry has its unique fasteners, usually to prevent unauthorized access to dangerous or proprietary equipment, such as electrical vaults and electronic hardware. Some of these tools, such as the Leatherman, are known across industries.

A whistle includes a housing having a chamber, and having a mouthpiece extended from the housing for engaging with a mouth of a user, the housing includes a partition provided in the chamber for separating the chamber the housing into two compartments, and includes two openings communicating with the compartments of the housing respectively, and includes one or more channels communicating with the compartments and the openings of the housing respectively, and two peas are received and engaged in the compartments of the housing respectively for generating sounds of different pitches and/or tones. The peas include different shapes, or the peas include different diameters.

An improved implementation of the electronic whistle sensor provides more accuracy in determining if the whistle has sounded, utilizes a ubiquitous sensor, and enables versatility in the signaling device.

A set of two or more whistles. Each whistle of the set sounds differently from each other based on a different type of sound or a different value of a characteristic of sound common to whistles of the set. Sound characteristics may include but not limited to pitch, quality, loudness, and/or duration. Each whistle in the set may be different in appearance from each other in the set. Appearance characteristics may include but not limited to color, numbering, design, light up features, size, and/or shape. Alternatively, the whistles in a set may have a common appearance characteristic, but each whistle may have its own value of the common appearance characteristic. Additional element(s) such as lanyards or mouthpieces may be added to whistles of a set to distinguish them from each other. The set of whistles may be included in a kit having a box for removably storing the whistles.

A water-powered residential fire suppression and alarm system is provided. The system comprises a sprinkler head, a water-powered alarm, a fire-resistant transfer line assembly, and a housing assembly. The sprinkler activates upon excessive heat. An unclosable channel connects the alarm with the sprinkler head. The transfer line assembly includes a fire-resistant transfer line connected the alarm and to a multi-port coupling. The multi-port coupling also connects to an existing water fixture. The transfer line assembly is unclosable. The housing assembly has a housing with a vertical span of about 3-12 inches. The sprinkler head and alarm are mounted to the housing assembly and the transfer line assembly is connected to the housing assembly. The transfer line assembly connects to the sprinkler head directly as well as through the alarm. When water is provided to the coupling and the sprinkler head activates, water flows through the transfer line, activating the alarm.

An upper plate and a similarly configured lower plate each have a serpentine forward edge, a linear rearward edge, a left edge, a right edge, an upper surface, and a lower surface. The upper and lower plates each have a whistle section and a laterally spaced bottle-opener section. A C-shaped bend couples the upper and lower plates. An upper hole extends through the upper plate in the whistle section. An axially aligned lower hole extends through the lower plate in the whistle section. A J-shaped notch extends through the upper plate and the lower plate and the C-shaped bend at the rearward edge in the bottle-opener section.
