A surgery apparatus includes a resilient foam pillow having an arrangement of labeled tabs for holding lines leading to/from a patient during and after surgery. A central cutout area in the pillow accommodates the patient's eyes, nose and mouth when in the prone position. Left and right channels in the foam pillow extend from a top edge of the pillow to the central cutout area for holding a breathing tube system. The foam pillow further includes a removably attachable chest support and opposite shoulder supports. A multipurpose holder device for placement on the patient's head has an arrangement of straps for securing an eye shield, a bite block and ventilator tube securing straps on the patient during surgery.

Systems and methods for adjusting a user's circadian rhythm are provided. In some embodiments, a system may be configured to obtain information relating to the user's present circadian rhythm and information relating to one or more anticipated times of sleep and/or wakefulness. The system may generate a model for estimating the user's circadian rhythm. The system may also generate a model for estimating the user's homeostatic sleep drive. Based on one or both models, the system may generate instructions for activating the light source to adjust the user's circadian rhythm.

Improved wearable optics is disclosed. The wearable optics comprises a frame member and a lens. The wearable optics also includes circuitry within the frame member for enhancing the use of the wearable optics. A system and method in accordance with the present invention is directed to a variety of ways to enhance the use of eyeglasses. They are: (1) media focals, that is, utilizing the wearable optics for its intended purpose and enhancing that use by using imaging techniques to improve the vision of the user; (2) telecommunications enhancements that allow the eyeglasses to be integrated with telecommunication devices such as cell phones or the like; and (3) entertainment enhancements that allow the wearable optics to be integrated with devices such as MP3 players, radios, or the like.

An eye shield for protecting a user's eye has a shield that includes an aperture. The aperture has a first central axis, a medial side, and a lateral side, and a gasket that is coupled to the shield and disposed within the aperture. The gasket has a second central axis. The first central axis is at an oblique angle relative to the second central axis.

A protective shield is provided for covering a self-contained breathing apparatus (SCBA) mask or a full- face air purifying respirator (APR) lens to prevent damage and scratching. The shield consists of a die cut shape of thermoplastic sheet that duplicates the outline of the self-contained breathing apparatus mask lens and/or frame. The protective shield can be produced using various grades, colors and/or densities of material replicating limited visibility or blackout conditions. To protect the majority of the plastic lens, the shape of the shield includes a peripheral overlap onto the mask utilizing the SCBA lens frame. The shield can be attached to the self-contained breathing apparatus face mask by means of any of the following: bungee, hook, or elastic cord; all of which allows the shield to be attached or removed quickly. Many SCBA/APR training exercises require limited visibility. The invention can be used as an effective training tool to prevent light transmission and simulate extremely limited visibility.
