Abstract: A protective case for an electronic device is disclosed. The protective case may also provide a light source to be used with the front-side camera and the backside camera of the electronic device. The light source may pivot between different positions in order to emit light in the proper direction. The protective case may also include at least one power source to power the electronic device as well as the light source.

Abstract: A device and method for advertising a product or service are described herein. The device may take a photograph of a participant holding the product or a thing representing the service. The participant identifies a product identifier of the product or service or the device. The product identifier and the photograph are uploaded to a third-party server that subsequently uploads basic product information and the photograph to the participant's online social network for viewing by the participant's contacts. The participant has a self-interested goal of presenting only relevant products and services to his or her contacts to maintain credibility.

Abstract: An exercise machine adaptable to perform a cardiac workout and an abdominal workout simultaneously includes a frame structure, a resistance provider, a pair of pedals, a first sprocket, a second sprocket, a sprocket rotating means, an axis, an engaging means, a cable, a seat, an elastic band, a pair of shoulder straps, a monitor and a pulley system. The sprocket rotating means allows the first sprocket to engage and disengage with the exercise bike. The pedaling of the pedals allows the user to perform the cardiac workout. The pair of shoulder straps designed to insert along the shoulders of the user is connected to the cable and creates a tensional force thereon by getting stretched with the pedaling of the pedals. The tensional force pulls the user backward and the user in turn resists the backward movement by manually contracting abdominal muscles to perform the abdominal workout.
