Abstract: Package-receiving-lockers (PRLs) may have a collapsible-locker portion and door-attachment-structure. PRLs may exist in a substantially collapsed configuration for storing the given PRL or for otherwise minimizing a footprint of the given PRL; and these PRLs may exist in a substantially deployed (expanded) configuration for acting as a secure object storage location. Regardless of configuration (deployed or collapsed), PRLs may be removably attached to side-hinged-doors with the door-attachment-structure, in such a way so as not to impair operation of the given door. The PRLs may have various electronics for facilitating access (e.g., locking and unlocking the collapsible-locker), delivery confirmation, and mitigating theft. These electronics, along with specialized software, may allow an intended recipient (e.g., a buyer), a shipper/delivery person (or shipping/deliver robot), and/or a seller/vendor to access the PRL in a controlled and documented manner.

Abstract: The present invention relates to training devices of types commonly referred to as strike pads, strike mitts, focus mitts, strike dummies and double end bags, which are used in many forms of martial arts, self-defense, unarmed combat, fighting and fitness training. The strike head of the invention is a martial arts, fighting and fitness training device in the shape of an anatomically accurate human head that provides realistic size, surface features and yield characteristics for highly accurate, targeted and dynamic hand strikes, arm strikes and kicks. The device can be held in place for the training athlete through various means including; 1) an integrated internal handle oriented to afford the holder an ergonomically advantageous shape, contour and orientation, 2) a double end rope suspended from the floor and ceiling, and/or 3) a fixation attached to a floor, wall or overhead mounted post or armature.
