Abstract: In general, some embodiments described herein relate to using agile or dynamic addresses for multicasting that may be difficult or impossible for a malicious actor to predict. Such agile addresses may prevent a malicious actor from attacking a single static multicast address and may prevent the architecture of the multicast network from propagating the attack. Data sent to invalid (e.g., expired, revoked, and/or otherwise depreciated addresses) can be filtered out and dropped from the network. For example, a first group key associated with a first time period can be calculated based on a first shared secret and a second group key associated with a second time period can be calculated based on a second shared secret. At any given time at least one group key can be an accepted group key. When a multicast address includes a currently accepted group key, the data can be sent to a group.

Abstract: A pick system includes a holder and a pick assembly. The holder includes a first end, a second end, and a bore extending between the first end and the second end and defining a longitudinal axis. The surface of the bore may be tapered so that the diameter of the bore proximate the first end is greater than the diameter of the bore proximate the second end. The pick assembly includes a shaft. The shaft is received within the bore of the holder along the longitudinal axis, and the shaft may be tapered to mate with the bore.

Abstract: Some embodiments described herein relate to a method that can include receiving, at a first time, first data for routing to a group. The first data can be sent to the group via a first multicast address that is based, at least in part, on a first key associated with a first time period and derived from a first shared secret. At a second time, second data for routing to the group can be received. The second data can be sent to the group via a second multicast address that is different from the first multicast address. The second multicast address can be based, at least in part, on a second key associated with a second time period and derived from a second shared secret.

Abstract: A rear frame assembly is provided for use in an automotive vehicle extending between upright side walls to define a trunk opening. The rear frame assembly includes a cross car beam extending laterally between the side walls of the vehicle. A sail panel is fixedly secured to the cross car beam. The sail panel includes symmetrically opposite flanges adapted to conform to the side walls of the vehicle to define a path for diverting a flow of water around the trunk opening. The sail panel includes a conically shaped concavity for engaging a conical protrusion on the vehicle for locating the rear frame assembly within the vehicle during installation of the rear frame assembly to the vehicle.
