In an aspect, an apparatus is provided and includes an air-tight object having an outer layer, an inner layer, and a cover, and a light module. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines a first aperture and a second aperture. The inner layer and the cover define a first interior region. The inner layer defines a second interior region. The light module is encapsulated within the first interior region and is configured to send light through the inner layer, through the second interior region of the air-tight object, and through the second aperture of the outer layer, wherein the cover is disposed between the light module and the outer layer.

Disclosed are an exercise ball as well as a system, method and computer program product for monitoring the use of the exercise ball by a user. An exemplary system comprises: a first data processing unit; an exercise ball comprising a shell and a monitoring unit operatively associated with the shell, said monitoring unit comprising at least one sensor for detecting a parameter representative of the movement of the exercise ball by the user, the first data processing unit being configured to determine and provide the user with data representative of the use of the exercise ball by the user based on parameters representative of the movement of the exercise ball by the user detected by said at least one sensor.

At least one exemplary embodiment is directed to an earpiece having a balloon and a stent where the balloon is mounted on the stent and the stent incorporates two or more channels including at least an inflation channel and an acoustic channel. In some embodiments the stent is configured to pass audio signals through the acoustic channel where the acoustic channel is independent of the inflation channel of the balloon. Other embodiments are disclosed.

A filling device may be used to fill a ball or other inflatable item from a water source such as a hose. A filling device may include an adapter having a cylindrical body with a hollow threaded interior, one closed end and one open end. A filling coupler is coupled to the one closed end of the cylindrical body. The one closed end of the cylindrical body has an opening formed therethrough and the filling coupler is coupled to the one closed end covering the opening. The filling coupler has a hollow threaded interior in fluid communication with the opening. A tip may be removably coupled to the filling coupler. The tip may be a ball inflation needle, a water balloon filling tip or the like.

An exercise device includes a resilient compression member configured to be placed between inner thighs of a user and resist a compressive force from the inner thighs and gluteals of the user. The exercise device also includes a resilient tension member configured to couple to opposing sides of the compression member, form a first portion of a loop around the compression member and outer thighs of the user, and resist a tensile force from the outer thighs of the user. The exercise device also includes an extension member configured to connect with opposing ends of the tension member to form a second portion of the loop around the compression member and outer thighs of the user.

The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second. The inflatable article or bladder of the present invention may be used as or in athletic equipment, for example, including footwear.
