Abstract: The present disclosure relates to a short-range communication device (10, 10?, 5 10?) for a personal protective equipment or a personal protective device (200, 210, 220, 230) comprising a transmission unit (20, 20?, 20?) for wirelessly transmitting a voice signal of a user (100, 110, 120, 130, 140, 150, 160) to a receiving unit (40,40?, 40?) over a predetermined distance such that a communication channel is established between the transmission unit (20, 20?, 20?) and the receiving unit (40, 40?, 40?) so that a user (100, 10 110, 120, 130, 140, 150, 160) can hear the voice signal. The present disclosure further relates to a short-range communication system comprising at least two short-range communication devices (10, 10?, 10?) according to the present disclosure and to a method of establishing a short-range communication between such devices (10, 10?, 10?).

Abstract: Methods, systems, and devices for manufacturing a custom orthotic sandal. The described techniques may include generating a footbed model for a subject's foot based at least in part on a foot model. The foot model may be obtained by scanning the foot of the subject. One or more transforms may be applied to the footbed model. The one or more transforms may include expanding the footbed model along one or more bisection lines. The modified footbed model may extruded in at least one dimension to obtain a midsole model. A sandal midsole may be manufactured out of a material according to the midsole model. The sandal midsole may be used in the custom orthotic sandal.

Abstract: A saw guard for attachment to a riving knife of a table saw includes a body portion having an elongated shape. The body portions defines a guard portion configured to cover a portion of a saw blade and an attachment portion. The attachment portion extends from the guard portion and defines a slot configured to receive the riving knife. The saw guard further includes an anchor piece connected to the body portion and arranged at least partially in the slot. The saw guard further includes an attachment assembly connected to the body portion and arranged at least partially in the slot and separated from the anchor piece. In a first configuration, the anchor piece and the attachment assembly may define a two-point attachment between the saw guard and the riving knife. In a second configuration, the attachment assembly may permit release of the saw guard from the riving knife.
