Abstract: A lockdown system for use in a building including one or more rooms, each having a door providing access thereto, and common areas exterior or the one or more rooms, the lockdown system including a plurality of lockdown initiation devices positionable in the building in one or more of the one or rooms and/or the common areas exterior of the one or more rooms, the plurality of lockdown initiation devices each being independently manually activatable to signal initiation of a lockdown event and to communicate, via a wireless communication network, one or more state-indicating signals indicating when the lockdown initiation device has been manually activated to signal initiation of a lockdown event, whereupon the signaled initiation of the lockdown event is communicated to at least one communication device and an alert notification of the initiation of the lockdown event is provided via the at least one communication device.

Abstract: A lockdown system for use in a building including multiple rooms with doors providing access to the rooms, the lockdown system including: at least one room lockdown component provided in each of a plurality of the rooms, the room lockdown components comprising door-securing devices that are external of the doors and, in a deployed condition of the room lockdown components, are manually positioned inside said rooms to oppose inward movement of the doors and thereby block or secure the doors, the room lockdown components further characterized by a non-deployed condition in which the door-securing devices are positioned at storage locations inside the rooms, and wherein further each room lockdown component is operative to automatically signal initiation of a lockdown event when its door-securing device has been moved from its storage location; and at least one communication device operative to receive the signaled initiation of a lockdown event when any one or more of the door-securing devices have been moved fr

Abstract: A building lockdown system for a building with multiple rooms with doors providing access to the rooms, the system including smart light fixtures positioned inside and outside at least some of the rooms, at least some of the smart light fixtures configured to be selectively illuminated in each of a plurality of colors, and room lockdown components provided in the plurality of rooms, the room lockdown components adapted to block or secure the doors of the rooms against opening in a deployed condition of the lockdown components. The smart light fixtures and the room lockdown components are equipped with BLE sensors defining a BLE mesh network. The room lockdown components are adapted to communicate, via the BLE mesh network, whether they are in the deployed condition thereof, and are further adapted to provide audio and/or visual signals.

Abstract: Shoulder dystocia occurs most frequently during the birth of large infants, where the shoulders remain impacted, and lateral traction on the fetal neck with evulsion of the brachial plexus may cause brachial plexus injury. The idea is to prevent excessive lateral bending of the infant's head, its ensuing stress, and damage to the brachial nerve bundle. This invention consists of a special head brace, which limits the lateral movement of the baby's head with respect to the clavicle, and can be quickly mounted when required by the specific medical situation. Its design in two sections provides a snug fit, regardless of the infant's head size, and permits its installation in the little time available to complete the birth process.

Abstract: The invention consists of a bent flat member, which, properly inserted in the vagina, may be used to help a patient affected with rectocele (hernia) eliminate fecal matter, which otherwise may remain in the pocket formed by the hernia, and cause medical problems. The instrument is washable and may be indefinitely re-used by the patient.

Abstract: The invention consists of an umbrella-like section used in an inverted vertical position as a funnel to receive rain water. The center of this foldable funnel is open and allows the water to flow out. The funnel is positioned over a vertical tubular housing, which has the dual purpose of channeling the water to a cistern, and to serve as the housing for the folded funnel. A mechanism consisting of a system of pulleys, and optionally electric motor, extracts and retracts the funnel as required by either human intervention, or automated logical decisions of a control device, or a combination of both, according to the degree of sophistication desired.
