Abstract: Thermoplastic bags with phased deformation patterns are described. In particular, one or more implementations comprise thermoplastic bags with ring rolling, SELFing, or other deformation patterns phased or aligned relative to the sides of the bags. The phased deformation patterns can allow for reducing or eliminating deformation patterns in areas of the thermoplastic bag in which side seals or other seals are formed. Additionally or alternatively, the phased deformation patterns can provide for zones that provide differing properties (e.g., functional or aesthetic). Such zones can vary aligned along a width of the thermoplastic bag and optionally also vary along a height of the thermoplastic bag. The differing zones can provide the thermoplastic bags with phased deformations that provide leak prevention, liquid containment, and other benefits.

Abstract: To assist a user device of a 5G or 6G network in finding its downlink messages, the base station can attach a leading and trailing demarcation to the message. The user device can recognize the demarcations, extract the data between them, and thereby receive the message without computation-intensive searching. Advantageously, the user device can request that the base station not transmit DCI (downlink control information) messages to the user device, since the user device can readily find its messages according to the demarcations. In various embodiments, the demarcations can indicate the address or identity of the intended recipient, the length of the message, the type of the message, and other information to assist the user device. In addition, for even easier detection of the demarcations, the base station can insert a gap of no transmission before and/or after each demarcation. Such demarcations may enable low-cost reduced-capability user devices.
