Self-evaluative appraisals of coping capability and posttraumatic distress following motor vehicle accidents.

Abstract: This study tested the importance of coping self-efficacy (CSE) perceptions and change in perceptions of CSE for recovery from motor vehicle accident (MVA) trauma. Data were collected 7 days following the accident (Time 1; n = 163), 1 month after the accident (Time 2; n = 91), and 3 months after the accident (Time 3; n = 70). Early changes in CSE (i.e., from Time 1 to Time 2) predicted posttraumatic distress at 3 months after MVA trauma, even after controlling for Time 1 or Time 2 posttraumatic distress and other trauma-related variables (i.e., accident responsibility, litigation involvement, and peritraumatic dissociation). Early changes in CSE perceptions, however, neither moderated nor mediated the effects of early posttraumatic distress (Time 1) on 3-month posttraumatic distress. Time 2 CSE levels, however, did mediate the relationship between acute posttraumatic distress (Time 1) and 3-month posttraumatic distress (Time 3). These findings highlight the importance of early interventions aimed at strengthening self-efficacy after MVA trauma.

SAIDuCANT: Specification-Based Automotive Intrusion Detection Using Controller Area Network (CAN) Timing

Abstract: The proliferation of embedded devices in modern vehicles has opened the traditionally-closed vehicular system to the risk of cybersecurity attacks through physical and remote access to the in-vehicle network such as the controller area network (CAN). The CAN bus does not implement a security protocol that can protect the vehicle against the increasing cyber and physical attacks. To address this risk, we introduce a novel algorithm to extract the real-time model parameters of the CAN bus and develop SAIDuCANT, a specification-based intrusion detection system (IDS) using anomaly-based supervised learning with the real-time model as input. We evaluate the effectiveness of SAIDuCANT with real CAN logs collected from two passenger cars and on an open-source CAN dataset collected from real-world scenarios. Experimental results show that SAIDuCANT can effectively detect data injection attacks with low false positive rates. Over four real attack scenarios from the open-source dataset, SAIDuCANT observes at most one false positive before detecting an attack whereas other detection approaches using CAN timing features detect on average more than a hundred false positives before a real attack occurs.

Variation of digital SET pulse widths and the implications for single event hardening of advanced CMOS processes

Abstract: Single event transient (SET) pulse widths produced from heavy ion irradiation in digital ICs are measured using a variable-delay temporal-latch test structure We show for the first time that there is a wide distribution of SET pulse widths created by heavy ion radiation in digital CMOS logic at given linear energy transfer (LET) levels We were able to measure SET pulse widths from as short as 344 ps to greater than 15 ns in 018 /spl mu/m CMOS technology at LETs greater than 80 MeV-cm /sup 2//mg Depending on LET, the cross section of the very long SET pulses were as much as four orders of magnitude smaller than for the shorter pulse widths This has substantial implications for hardening techniques; specifically, we now know that we can dramatically improve the SET hardness without suffering the speed penalties required to remove the longest transients

Three-cell wireless communication system

Abstract: A wireless communication system including a repeated pattern of cells, in which base station transmitters and user station transmitters for each cell may be assigned a spread-spectrum code for modulating radio signal communication in that cell. Radio signals used in that cell are spread across a bandwidth sufficiently wide that both base station receivers and user station receivers in an adjacent cell may distinguish communication which originates in one cell from another. Adjacent cells may use distinguishable frequencies and distinguishable codes, but it is sufficient if adjacent cells use distinguishable frequencies and identical codes. A repeated pattern of cells allows the codes each to be reused in a plurality of cells.

Method and System For Notifying A User of An Event Or Information Using Motion And Transparency On A Small Screen Display

Abstract: A method and system for notifying a user of an event or information using motion and transparency on a small screen display are provided. When an in-application event occurs or an indication that a new event has occurred, a notification window is created off display, and graphically animated on top of the current application display, in a small window which is un-obtrusive to user interaction in the active application. A user may set preferences for display location, size, transparency, color, time displayed, and content, and each window may vary based on the notification type, allowing users to quickly glance and identify the information displayed. The alert information may be summarized and or prioritized based on notification types,
