Abstract: A container is disclosed, generally having an open top defined by an annular rim, a base, and a sidewall extending between the top and the base. The sidewall has two arcuately formed longitudinal recesses, an annular rib, an annular shoulder located between the longitudinal recesses and the base, and a lower portion extending between the annular shoulder and the base. The annular shoulder is characterized by two arched portions aligned with the longitudinal recesses, and the lower portion has two beveled portions aligned with the longitudinal recesses. This container is more ergonomic, and has greater sidewall strength and rigidity, than existing containers.

Abstract: A self-contained laser generator uses a laser diode and a mirror to generate a laser light beam, split it into two parts, and generate perpendicular beams of laser light. One of more mirrors are useful for receiving light and splitting it into two beams. An internal motor then rotates the mirrors and one of the beams becomes a rotating laser light, useful for aligning objects in a horizontal or vertical direction. The other beam may be used to locate and orient the rotating laser line generator in a different plane.

Abstract: A computer having a control panel for directly controlling software and hardware of the computer, eliminating the necessity of navigating software to control such functions. These direct controls can include audio CD controls, telephone answering machine controls, instructional software controls, power setting controls, and volume controls.

Abstract: A light bar for mounting on an emergency vehicle to provide warning light signals. An elongate body portion has an elongate axis, the elongate body portion adapted to be mounted on the emergency vehicle so that the elongate axis traverses an axis coaxial with the direction of the travel of the emergency vehicle. At least three vertically spaced lighting layers are provided, each layer having at least one emergency light source, the emergency light sources on each layer cooperating to provide a transient high intensity warning light signal 360.degree. around the light bar. At least four linear rows of emergency light sources as viewed from the top of the light bar are also provided, the rows being substantially parallel to the elongate axis, each row having at least two emergency light sources, at least one row located in each of the layers and at least one layer having at least two rows, the emergency light sources in each row cooperate to provide a transient high intensity warning signal 360.degree.
