Forensic crash investigation often requires developing detailed profiles showing the location and extent of vehicle damage to identify impact areas, impact direction, deformation, and estimated vehicle speeds at impact. Traditional damage profiling techniques require extended and comprehensive setups for mapping and measurement that are quite labor- and time-intensive. Due to the time involved, this damage profiling is usually done in a remote holding area after the crash scene is cleared. Light detection and ranging (LiDAR) scanning technology in consumer handheld electronic devices, such as smartphones and tablets, holds significant potential for conducting this damage profile mapping in just a few minutes, allowing the mapping to be conducted at the scene before the vehicle(s) are moved. However, there is limited research and even scarcer published literature on field procedures and/or accuracy for these emerging smartphones and tablets with LiDAR. This paper proposes a methodology and subsequent measurement accuracy comparisons for survey-grade terrestrial laser scanning (TLS) and handheld alternatives. The maximum root mean square error (RMSE) obtained for profile distance between handheld (iPad) and survey-grade TLS LiDAR scans for a damaged vehicle was observed to be 3 cm, a level of accuracy that is likely sufficient and acceptable for most forensic studies.

M-learning utilizes handheld electronic devices as didactic tools for facilitating learning and teaching within real-time access in the language classroom. Current studies on m-learning suggest that the incorporation of electronic devices can lead to greater student engagement and better performance. Using a questionnaire, 22 professors from the major Bachelor’s in the Teaching of English as a Foreign Language from the Universidad Nacional (Costa Rica) were surveyed about how mobile devices are being implemented in the language classroom.

The electronic receivers of global navigation satellite systems (GNSSs) are implemented in various handheld electronic devices such as laptops, smartphones, and smartwatches; therefore, their dimensions are of critical importance. Achieving a GNSS terminal of a small size is difficult due to its relatively low operational frequency (L-band), which is equivalent to a wavelength of approximately 24 cm. As an efficient half-wavelength antenna is too large for compact devices, in this paper, an electrically small antenna (ESA) for GNSS terminals is presented. The antenna was miniaturized by using a dielectric block with relatively high permittivity, making some parts virtual, and optimizing its geometry. The operational frequency of the ESA is tunable by means of metallic rods of variable heights inserted into a cylindrical cavity drilled inside the dielectric block. The results confirm the feasibility of the concept and the usability of the ESA for compact GNSS terminals.

Aim: This study evaluated the patient experience of receiving subcutaneous chemotherapy at home via a unique ‘Cancer Treatment at Home’ outreach service adapted by the UK Clatterbridge Cancer Centre NHS Foundation Trust. Patients & methods: The service involved using highly trained nurses to deliver cancer treatments to patients in their own homes. Patient outcomes were monitored over 12 months via the Systemic Anti-Cancer Therapy at Home (SACT) survey using handheld electronic devices. Results: Of the 56 participating cancer patients, 53 provided responses. Patients received subcutaneous trastuzumab, denosumab, pembrolizumab, fulvestrant and goserelin. Overall, 96% of respondents were ‘very satisfied’ and 4% ‘satisfied’ with the service. All respondents would recommend the service to others. Conclusion: The ‘Cancer Treatment at Home’ service has improved the patient experience for cancer care and has been recognized nationally for its achievements.
