This work presents a robotic-based solution devised to automate the product packaging in industrial environments. Although the proposed approach is illustrated for the case of the shoe industry, it applies to many other products requiring similar packaging processes. The main advantage obtained with the automated task is that productivity could be significantly increased. The key algorithms for the developed robot system are: object detection using a computer vision system; object grasping; trajectory planning with collision avoidance; and operator interaction using a force/torque sensor. All these algorithms have been experimentally tested in the laboratory to show the effectiveness and applicability of the proposed approach. [ABSTRACT FROM PUBLISHER]

OBJECTIVE: To determine whether alterations in random events, as measured by a Random event generator (REG), occur in association with a bioenergy healing practice. DESIGN AND SETTING: Two REGs were set up and run in parallel: one in a bioenergy healer's office and another at a local library as a control. Two multiday sets of data were collected in each setting. A third set was collected in which a reduced amount of attention was placed on the REG by the healer. REG excursions were calculated and compared for (1) overall days in the library and bioenergy healer's office, (2) healing and nonhealing phases in the healing office, and (3) overall excursions during high(sets 1 and 2) and low attention (set 3) by the healer. RESULTS: The library REG produced excursions outside the 95% confidence interval (CI) on 35 of 61 days (58%), and the REG in the healing practice 47 of 51 days (92%) (mean difference, 34%; 95% CI, 18% to 49%; chi(2) = 16.3, 1 df, p < 0.0005). In the healer's office, 0.6496 excursions per segment for healing phases and 0.6548 excursions per segment for nonhealing phases were shown (t = -1.3, 6794 df, p = 0.182). A comparison with chance expectation derived from Monte Carlo runs showed significantly less mean excursions per segment (t = -7.8, 36625 df, p < 0.0005) for healing phases and no difference in nonhealing phases (t = -0.16, 6309 df, p = 0.872). There was no significant difference in excursions between the high- and low-attention situations in the healing practice. CONCLUSIONS: In the presence of a healer, an REG produced greater than chance excursions more often than a control REG in a library setting. The healing and nonhealing phases demonstrated inconsistent results. REG deviations were not influenced by the amount of attention directed toward the machine. [ABSTRACT FROM AUTHOR]

The Myocardial Infarction Triage and Intervention Trial of prehospital versus hospital administration of thrombolytic therapy markedly reduced hospital treatment times, but the 2 groups had similar outcomes. However, patients treated < 70 minutes from symptom onset had better short-term outcomes. The purpose of this study was to determine the long-term influence of very early thrombolytic treatment for acute myocardial infarction. A total of 360 patients were followed for vital status and cardiac-related hospital admissions over a period of 34 +/- 16 months. Patients enrolled in the trial had symptoms for < or = 6 hours, ST-segment elevation on the prehospital electrocardiogram, and no risk factors for serious bleeding. They received aspirin and recombinant tissue plasminogen activator either before or after hospital arrival. Primary end points in this study included long-term survival and survival free of death or readmission to the hospital for angina, myocardial infarction, congestive heart failure, or revascularization. Two-year survival was 89% for prehospital- and 91% for hospital-treated patients (p = 0.46). Event-free survival at 2 years was 56% and 64% for prehospital- and hospital-treated patients, respectively (p = 0.42). In patients treated < 70 minutes from symptom onset, 2-year survival was 98%, and it was 88% for those treated later (p = 0.12). Two-year event-free survival was 65% for patients treated early and 59% for patients treated later (p = 0.80). In this trial, poorer long-term survival was associated with advanced age, history of congestive heart failure, and coronary artery bypass surgery performed before the index hospitalization, but not with time to treatment.
