A neck shade accessory for baseball caps has a support band, at least one attachment clip, and a sunshade. The support band is adjustable in length and curved to conform to the rear and sides of a baseball cap. Each attachment clip is secured to the support band and clips onto the brim of the baseball cap. The sunshade is terminally attached along the support band and hangs from the rear of the baseball cap to protect a wearer's neck and shoulders from exposure to the sun. A shade attachment of the sunshade may further be incorporated to secure the sunshade to an adjustment band positioned at the rear of the baseball cap.

A sweat-absorbing pad for use with a headwear having a sweatband, which includes a body with a front surface that is configured to contact, at least in part, a user's head or forehead to absorb sweat; and a first clip. The first clip includes a clip body which includes a base, first and second legs, and a clip arm. The first and second legs extend from the base, and the clip arm extends from the base. The clip arm is substantially parallel to the first and second legs, and the clip arm is resilient to bias against the clip body. The clip body is substantially received in the body. Furthermore, the first clip, configured to receive at least a portion of the sweatband, fitted in between the body and the clip arm, such that the sweat-absorbing pad is detachably fixed to the sweatband.

The hat flag comprises a flag mount and a replaceable flag assembly. The flag mount may be coupled to a hat and may present a threaded receiver for detachably coupling the replaceable flag assembly to the top of the hat. The replaceable flag assembly may display a flag elevated above the hat via a flag support rod when the replaceable flag assembly is detachably coupled to the flag mount. The replaceable flag assembly may comprise a spring-loaded base such that the flag support rod may tilt when an external force is applied and may right itself when the external force is removed. The replaceable flag assembly may comprise a bearing such that the flag is free to swivel.

A removable cooling apparatus for a hat spaces a headband of the hat away from a wearer's head, creating an air gap that allows air flow over the wearer's head. A removable cooling apparatus uses coupling structures to hold the removable cooling apparatus in place against the headband. The removable cooling apparatus can be removed completely from the hat when not needed or for cleaning, leaving the hat in an unaltered state. A removable cooling apparatus may use a thin flexible strip to keep the headband of the hat from falling open into the air gap created by the removable cooling apparatus. The removable cooling apparatus use compressible pads to space the headband away from the wearer's head. The contact location of the compressible pads with the wearer's head can be easily adjusted by the wearer.

Apparatus for applying Transcranial Magnetic Stimulation (TMS) to a patient, the apparatus including a head mount for disposition on the head of a patient; and a plurality of magnet assemblies for releasable mounting on the head mount, wherein each of the magnet assemblies includes a magnet for selectively providing a rapidly changing magnetic field capable of inducing weak electric currents in the brain of a patient so as to modify the natural electrical activity of the brain of the patient; wherein the number of magnet assemblies mounted on the head mount, their individual positioning on the head mount, and their selective provision of a rapidly changing magnetic field is selected so as to allow the spatial, strength and temporal characteristics of the magnetic field to be custom tailored for each patient, whereby to provide patient-specific TMS therapy, to assist in diagnosis or to map out brain function in neuroscience research.

An apparatus to facilitate surveillance is disclosed. The apparatus includes a head-worn article, including an opening in the rear the article, a video camera mounted inside of the article, having a lens positioned at the opening to capture video data from the rear of the article and a transceiver to wirelessly transmit the video data to a remote device and receive wireless signals from the remote device to control operation of the video camera.

Provided herein are wearable laser devices that provide an intuitive visual indication of a fixed radius around the wearer. Some embodiments include optical detectors that detect when two or more persons are in proximity with one another. The wearable laser devices may be used in a variety of applications, including, but not limited to, infection control, sports and entertainment.
